In order to make a doughnut, a circular piece of dough that has a diameter of 2 inches is cut out of the center of a larger circular piece of dough that is 5 inches in diameter. What is the surface area of the top of the doughnut? You may leave your answers in terms of π.
Answer:
1.5π
Step-by-step explanation:
Inner circle area = π
Outer circle area = 2.5π
surface area = 2.5π-π = 1.5π
HOPE THIS HELPS!
The surface area of the top of the doughnut is 21[tex]\pi[/tex] sq inch.
How to find the area of a sector of a circle?Sector of a circle is like slice of a circular pizza. Its two straight edge's having an angle, and edge's length(the radius of the circle) are two needed factors for finding the area of that sector.
Since the whole circle with radius 'r' units have 360 degrees angle on center of the circle, and its area is
[tex]\pi r^2 \: \rm unit^2, thus, as the angle lessens, this area gets lessened. 360 degree = > \pi r^2 \: \rm unit^2 area1 degree = > \pi r^2 \: \rm unit^2/360 areax degree = > \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Thus, area of a sector with edge length 'r' units and interior angle 'x' degrees is given as:
[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Given;
The diameter of inner dough=2inches
The diameter of outer dough=5inches
To find the surface area of doughnut
=surface area of outer dough - surface area of inner dough
= [tex]\pi[/tex]R^2-[tex]\pi[/tex]r^2
=25[tex]\pi[/tex]-4[tex]\pi[/tex]
=21[tex]\pi[/tex]
Therefore, the area will be 21[tex]\pi[/tex] sq inch.

( has a photo ) Mary is planning a costume party. She spent $375.00 as shown on the graph. How much of the money was spent, to the nearest dollar, on the following items?
1) On decorations?
2) On food?
3) On party hall rental?
4) On prizes?
5) On invitations?
Use the graph below to answer problems 6-10.
( thank you for the help<3 )
Answer: $30 on decorations, $65 on food, $80 on party hall rental, $30 on prizes, and $45 on invitations.
Step-by-step explanation:
Hello! You are told that she has spent $375.00. You know she spent $40 on costumes, $30 on prizes, $65 on food, $45 on candy, $80 on party hall rental, $40 on music, and $45 on invitations. You can fill what you know in for food, party hall rental, prizes, and invitations. You still don't know how much Mary spent on decorations though. To find this information out. Add all of the amounts that you already know and subtract the total from 375 to find the remaining amount Mary spent for decorations. 30 + 65 + 45 + 80 + 40 + 40 + 45 = $345. Subtract 345 from 375. 375 - 345 = 30. Your final answer is she spent $30 on decorations. Hope this helps you out! :)

Find the diameter of a circle if the circumference is 8 cm. Round to the nearest tenth.
Answer: 2.55
Step-by-step explanation:
To find the diameter you divide the circumference by pi (3.14).
The formula is d=c/π
8/3.14 is 2.547... and when rounded would be 2.55 or 2.6 if rounded.

The probability of landing on blue is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on orange.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
Answer: The statement "The probability of landing on blue is greater than the probability of landing on purple." is true.

To ride a roller coaster, a person must be at least 60 inches tall. Which inequality represents the height, h, a person must be to ride the roller coaster?
Group of answer choices
h < 60
h > 60
h ≥ 60
h ≤ 60
Thanks!
Answer: h ≥ 60
Step-by-step explanation:
≥ means more than or equal to
to be able to ride the roller coaster their height must be more than or equal to 60.
Answer: h ≥ 60
Step-by-step explanation:
h < 60 means that the height is less than 60
h > 60 means that the height is more than 60
h ≥ 60 means that the height is 60 or more
h ≤ 60 means that the height is 60 or less
So the answer would be h ≥ 60 because the height is at least 60 or more

use the expression 6.3×15÷3±6.8-28.09
to create an expression that includes a
set of parentheses so that the value of
the expression is 46.25
Answer:6.3×(15÷3+6.8)-28.09
Step-by-step explanation: Hello!
6.3×15÷3±6.8-28.09
You should probably use addition instead of subtraction so let's try:
First try the expression 6.3×15÷3+6.8-28.09
You have to make a set of parentheses. You should probably not include 6.3 in the parentheses so you can multiply whatever is in the parentheses by 6.3. You should also probably not include -28.09 in the parentheses because you will make a negative number in the parentheses that won't be able to be made positive. Try:
6.3×(15÷3+6.8)-28.09
6.3(5 + 6.8)-28.09
6.3(11.8)-28.09
74.34-28.09
=46.25
This is correct!

Answer:
Cubes needed to fill Prism 6: 116
The volume of Prism 6: 125
Step-by-step explanation:
First, multiply the length by the width. We can find these measurements by looking at the bottom diagonal line of the cubes.
Count how many sides are facing the front on the lowest side.
There are 5 squares facing forwards that are inside the Prism. Therefore the width/length is 5 cubic units.
Now count how many cubes it takes to go from the front side to the backside, or how many squares are facing the right. Remember this is a 3-dimensional object.
5 squares are facing the right, each belonging to the 5 cubes on the bottom of the prism.
Now count how many cubes are stacking. There are 5 cubes in the tower.
To find the volume, multiply all the measurements together.
Volume = Length x Height x Width (5 x 5 x 5)
Now to find how many cubes are needed to fill the prism, count how many cubes are already inside Prism 6.
Once you've found out how much the volume is, subtract the number of cubes inside the prism(9) from the volume(125).
125 - 9 = 116 cubes are needed to fill Prism 6.

A restaurant customer left 1.95$ as a tip. The tax was 4% and the tip was 15% of the cost including tax.
a. Which information is not needed to compute the bill after tax and tip?
b. What was the total bill?
Answer:
To figure out the total cost of the meal, you can use the following formula:
Total cost = (Tip + Tax) / (1 - (Tip % + Tax %))
In this case, the tax is 4% and the tip is 15%, so we can plug in the values to get:
Total cost = (1.95) / (1 - (0.15 + 0.04))
Now we can solve for the total cost:
Total cost = 1.95 / (1 - 0.19) = 1.95 / 0.81 = 2.40625$
Total cost= 2.40625$So the total cost of the meal was $2.40625, including tax and the tip left by the customer.

yuson must complete a certian number of hours of community service. she does 2 hours of service each day. after 8 days, yuson has completed half of her required community service. write a linear equation to represent the hours that yuson has left to do after x days.
Answer:
y = 32 -2x
Step-by-step explanation:
You want an equation for the remaining community service Yuson must complete after x days if she does 2 hours per day and is half done after 8 days.
RemainingYuson has completed (2 hr/day)·(8 day) = 16 hr of community service after 8 days. This is half the total required, so the initial amount required must be 2·16 = 32 hours.
After x days, 2x hours have been completed, reducing the amount remaining. Thus the amount remaining is ...
y = 32 -2x . . . . . hours left after x days

Plot 2 1/3, −5/6, and −3 1/2 on the number line.
When plotting fractions on a number line, we need to figure out how much each tick mark is. See the photo attached for how to plot 2 1/3, –5/6, and –3 1/2 on the number line.
The number lineOn a number line,
the left side shows smaller numbers, and;the right side shows greater (bigger) numbers.This number line also has negative numbers. Each tick is still worth the same on the entire number line, but leftward of 0, the numbers become negative.
How much is each tick mark?The vertical markings on the number line are called tick marks.
To get from one whole number to the next whole number on the number line, we have to count 6 tick marks. This means that each tick is 1/6.
Plot 2 1/3The dot will be between 2 and 3.
First, find 2.
[tex]\frac{1}{3} =\frac{1*2}{3*2}=\frac{2}{6}[/tex] Since 1/3 = 2/6, we then move right (get bigger) by 2 ticks.
See the photo below for the plotted dot. 2 1/3 is in red.
Plot –5/6The dot will be between -1 and 0.
Start at 0. Then, move left (get smaller) by 5 ticks.
See the photo below for the plotted dot. – 5/6 is in green.
Plot –3 1/2The dot will be halfway between –3 and –4.
First, find –3. Then, move left (get smaller) by 3 ticks.
See the photo below for the plotted dot. –3 1/2 is in blue.
