Answer:

Step-by-step explanation:
Hellllloooo!
One last time why dont we.
This time we are given a cylinder to find the area of which is pretty fun ngl.
Lets take a look at the formula for a cylinder :
Volume = [tex]\pi[/tex] x r² x h
Now this may look weird cause that house thing is for sure not a number but trust me it is easy once you know what you're looking at.
So that house thing is called pi, and really it is worth 3.14 just it looks like that for some reason. But it is used to find the area of circles.
So what we are going to do is find the area of the circle which is the base of the cylinder and multiply it by the height to find the total area.
Again lets see what we are given :
Radius = 8
Height = 15
Now we plug this into the formula :
Volume = [tex]\pi[/tex] x r² x h
Volume = [tex]\pi[/tex] x 8² x 15
(don't forget your little 2 after the radius (8))
So first lets do pi x 8²
=
Which gives us roughly around 201
So now we have the surface area of the base circle of this cylinder, all we have to do is multiply by the height.
So :
201 x 15
=
3015³
(don't forget your little 3 cause its 3D)
But that is your answer.
I hope this helps!

two points on a line L are (5,2) and (7,-4). what is the slope of L
Answer:
-3
Step-by-step explanation:
The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)
In this case we have:
(-4-(2))/(7-5)
(-6)/(2)
-3

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?
Answer:
7 paddleboards
Step-by-step explanation:
In order to solve this, you have to find the total amount that they earned by renting surfboards.
To find this you multiply 55 x 51 =2,805.
Then you use this factor and subtract it from the total amount they earned.
$3,300 - $2,805 = $495.
This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.
495/70 = 7
In conclusion, they rented out 7 paddle boards.
335.71 divided by 1000

If f(1) = 2 and f(n+1) = f(n)^2 – 3 then find the value of f(3).
Answer:
The value of f(3) = -2.
Step-by-step explanation:
First of all, let's find f(2).
[tex]f(n+1)=f(n)^{2}-3[/tex]
[tex]f(1+1)=f(1)^{2}-3[/tex]
[tex]f(2)=f(1)^{2}-3=2^{2}-3=1[/tex]
Now, we can find f(3):
[tex]f(2+1)=f(2)^{2}-3[/tex]
[tex]f(3)=f(2)^{2}-3=1^{2}-3=-2[/tex]
Therefore, the value of f(3) = -2.
I hope it helps you!

John paints blue spots on his car. He usually paints these blue spots in pairs. If the total count of blue spots is 72, how many pairs of blue spots are there?
Answer: 10 quarts of blue paint for every 2 quarts of green paint
Step-by-step explanation: The graph represents the relationship between the number of quarts of blue paint in the mix, xx and the number of quarts of yellow paint, yy.
The point (2 , 10) on the graph indicates 2 quarts of blue paint for every 10 quarts of yellow paint .
write the algebraic expression: The difference of 5 times a number and 11 is 17
Answer:
5x - 11 = 17
Step-by-step explanation:
Answer:
5x - 11 = 17
Step-by-step explanation:
Five times a number is 5x when the number is unknown.
The difference between that number and 11 is (difference means subtract)
5x - 11
All of which = 17
5x - 11 = 17

a rectangle has perimeter 86 cm and length 37 cm. what is its width
Answer:
6 cm
Step-by-step explanation:
37 × 2 = 74 cm86 - 74 = 12 cm12 ÷ 2 = 6 cmSo, the width is 6 cmI hope this helps!
Answer:
The rectangle's width is 6.
Step-by-step explanation:
You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:
86 = 2(37) + 2w
86 = 74 + 2w
Subtract 74 on each side.
2w = 12
Then, divide each side by 2.
w = 6
Hopefully this helped. And good luck in your studies.
