Find The Area Of The Shaded Region. Round Your Answer To The Nearest Tenth.please Help

Answers

Answer 1

Answer:

41.0 cm^2 to nearest tenth.

Step-by-step explanation:

Required area = Area of the semicircle - area of the clear triangle

Area semicircle = 0.5πr^2

= 0.5π *6^2

= 18π.

Finding Altitude h of the triangle :

cos 60 =  h / 6

h = 6 cos 60 = 6 * 1/2

= 3.

Finding Base b of the triangle:

sin 60 = 0.5b / 6

0.5b = 6 * sin 60

= 5.196.

So area of the triangle = h * 0.5b

= 3 * 5.196

Area of shaded region

= 18π -  3 * 5.196

= 40.96 cm^2

Answer 2

Answer:

38.52 cm²

Step-by-step explanation:

Take the shaded area to be found into 2 parts :

Left sectorTop area subtended by the chord

Area of left sector

As the area subtended by the chord takes up an angle of 120°, the remaining angle of the semicircle is :180° - 120° = 60°Area = πr² x (angle of sector)/360°Area = 3.14 x (6)² x 60/360Area = 3.14 x 36 x 1/6Area = 3.14 x 6Area = 18.84 cm²

Area subtended by top chord

Area (120° sector) - Area (triangle)Area = πr² x θ/360 - 1/2bhArea = 3.14 x 36 x 120/360 - 1/2 x 6 x 6Area = 3.14 x 12 - 18Area = 37.68 - 18Area = 19.68 cm²

Area (shaded)

Area (left sector) + Area (subtended by chord)18.84 + 19.6838.52 cm²

The length of a rectangle is three times its width.
If the perimeter of the rectangle is 64 cm, find its length and width.

Answers

Answer:

Length: 24 cm

Width: 8 cm

Explanation:

Let Width be "w"

Then Length is "3w"

=================

Perimeter of rectangle = 2(length+width)

===================================

2(3w+w) = 64(4w) = 32w = 8

So, width is 8 cm

Length: 3w ⇒ 3(8) ⇒ 24 cm

Answer:

Length = 24 cmWidth = 8 cm

Step-by-step explanation:

Given

Length = 3 x Width Perimeter = 64 cm

Solving

Perimeter = 2(Length) + 2(Width)Perimeter = 2(Length + Width)Perimeter = 2(3 x Width + Width)Perimeter = 2(4 x Width)Perimeter = 8 x Width64 = 8 x WidthWidth = 64/8 = 8 cmLength = Width x 3 = 8 x 3 = 24 cm

Fill in the blank to make the fractions equivalent. 10/16 and /8 ?

Step-by-step explanation:

To go from 10/16 to a bottom number/denominator of 8, you have to divide by 2.

Whatever you do to the top, you also do to the bottom, so you would divide 10, the numberator, by 2 to find the missing value.

The distance from earth to the moon is about 3.84 times 10^6 meters. what is one fourth of this distance

Answers

3.84 x 10^6 = 3,840,000

3,840,000 / 4 = 960,000

If the distance from the earth to the moon is about 3.84 x 10⁶.One-fourth of this distance will be 960,000

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, the distance from the earth to the moon is about 3.84 x 10⁶.

One-fourth of this distance is found by dividing the total distance by 4.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

Suppose the one-fourth of this distance will be x,

(1/4)× 3.84 x 10⁶ =x

x=(3.84 x 10⁶)/4

x=960,000

Thus, if the distance from the earth to the moon is about 3.84 x 10⁶. One-fourth of this distance will be 960,000

(05.01) A scale drawing of a kitchen is shown below. The scale is 1 : 20.
5 inches
4 inches
Show your work to determine the area of the room in square feet.

Answers

Answer:

500/9 or 55.56 ft²

Step-by-step explanation:

Find the dimensions of the kitchen, convert to feet

5 in * 20 = 100 in = 100/12 ft = 25/3 ft4 in * 20 = 80 in = 80/12 ft = 20/3 ft

The area is

25/3 * 20/3 = 500/9 = 55.56 ft² (rounded)

Answer:

5.56 ft² (nearest hundredth)

Step-by-step explanation:

Given:

width = 4 inlength = 5 in

If the scale is 1 : 20, then to scale up, multiply the width and length by 20:

⇒ width = 4 × 20 = 80 in

⇒ length = 5 × 20 = 100 in

Area = width × length

        = 80 × 100

        = 800 in²

1 ft = 12 in

⇒ 1 ft² = 12² in² = 144 in²

Therefore, to find the area of the room in square feet, divide the area in inches by 144:

⇒ area = 800 ÷ 144

            = 5.56 ft² (nearest hundredth)

The surface area of a cylinder is 432 pi yd2. The height of the cylinder is five times the radius. What is the diameter of the cylinder?

Answers

Since the surface area of this cylinder is [tex]432\pi \;yd^2[/tex], its diameter is equal to 12 yards.

How to calculate surface area.

Mathematically, the surface area (SA) of a cylinder is given by this formula:

[tex]S.A = 2\pi rh + 2\pi r^2[/tex]

Where:

h is the height.r is the radius.

Given the following data:

Surface area of cylinder = [tex]432\pi \;yd^2[/tex]Height = 5r.

Substituting the given parameters into the formula, we have;

[tex]432\pi = 2\pi r(5r) + 2\pi r^2\\\\432\pi = 2\pi 5r^2 + 2\pi r^2\\\\216=5r^2+r^2\\\\216=6r^2\\\\r^2=36\\\\r=\sqrt{36}[/tex]

r = 6 yards.

For the diameter:

Diamter = 2 x radius

Diamter = 2 x 6

Diameter = 12 yards.

In Texas, the average number of tornadoes in May was about 154% of the average number of tornadoes in April. Write and solve a proportion to find the average number of tornadoes that occurred in April.

Answers

The table of the average number of tornadoes is an illustration of proportions

The average number of tornadoes in April is 28

How to determine the average number of tornadoes in April?

From the table, we have:

Average number of tornadoes in May in Texas = 43

From the question, we have:

May = 154% * April

This gives

43 = 154% * April

Express as decimal

43 = 1.54 * April

Divide both sides by 1.54

April = 27.9

Approximate

April = 28

Hence, the average number of tornadoes in April is 28
