Question

Which measurement is closest to the area of the shaded region of the figure in square centimeters? Diameter is 10 cm. Base & height of square is 7

Answer 1

Answer:29.5

Explanation:

The diameter is 10 so the radius is 10/2 = 5

The area of the square is

A = s^2 = 7^2 = 49

The area of the circle is

A = pi r^2 = 3.14 * 5^2 =78.5

Subtract the area of the square from the area of the circle

l78.5-49 =29.5 thats all

Answer 2

29.5 cm^2

Explanation:

The diameter is 10 so the radius is 10/2 = 5

The area of the square is

A = s^2 = 7^2 = 49

The area of the circle is

A = pi r^2 = 3.14 * 5^2 =78.5

Subtract the area of the square from the area of the circle

78.5-49 =29.5
