A circle is drawn inside a square.
zhannawk [14.2K]

Shaded area = 21.46

Step-by-step explanation:

First find area of square,

Area = length × width

A = 20 × 20

A = 400 cm^2

Secondly, find area of circle

Area of circle = (π)r^2

A = (π)10^2

A = 100 π

Thirdly, find the area outside of the circle

Area of square - Area of circle

400cm^2 - 100π

= 85.84

lastly divide the answer by 4 to find the shaded area

85.84 ÷ 4

= 21.46

Consider the two functions given below.
mestny [16]
This means which transformation makes the same answer at x = 0

f(x) = 3x + 4
g(x) = {2}^{x}  - 1

f(0) = 4
g(0) = 1 - 1 = 0

Which transformation makes 4 = 0?

4 + x = 0 + y

4 - 3 =0 + 1

1 = 1

Option 1 is your answer

Here is an equation 2(x + 9) = -15. What are three different equations that have the same solution as that equation? Show or exp
igor_vitrenko [27]

Answer: 1) 2x+18=-15

2) -33+18

Step-by-step explanation: 1) multiply the outer number by the numbers inside the parentheses : 2 times x would = 2 because x is not by itself so it would be X=1x and you are multiplying 2x1 which = 2 and add the variable x so it would be 2×, and same with 18, you multiply 9x2 which =18 and thats how i got 2x+18 doesnt matter if i havent found the x yet because we already know what it equals to which is -15... 2) X=16.5 so to check we do 2×-16.5 which = -33 and add 18 it = -15

Maria makes a quilt. The main design is 5 feet long on each side. Then she adds a
fenix001 [56]

Answer:

1. 6 feet

2. 1 ft

0.5 ft

Step-by-step explanation:

The given dimensions for the quilt are;

The length of each sides of the quilt = 5 feet long, therefore, the shape of the quilt is a square

The area, A, of the finished quilt plus the border = 36 ft²

1. Given that the quilt's shape is that of a square, we have;

A = (side length)²

Side length = √A = √36 = 6 feet

2. Given that the initial length of the sides of the quilt are 5 feet, we have;

Increase in total length by border = Final length of quilt - Initial length of quilt

Increase in total length by border = 6 ft - 5 ft = 1 ft

The increase in total length of the quilt by the border = 1 ft

3) Given that the increase in the length by the border = 1 ft

The sum of the width of the border on both sides = 1 ft

Border width on one side + Border width on the other side = 1 ft

Since there is equal border width on each side of the quilt, we have;

2 × Border width = 1 ft

Border width = width of the border = 1 ft/2 = 0.5 ft.
