Question

Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use 3.14 as

an approximation for .
10 ft
A214 square feet
B54 square feet
C79 square feet
D22 square feet

Answer 1

Answer: choice D 22 sq feet

Explanation:

From the limited information, I will assume the sides of the square measure 10 feet

Square area is 10 * 10 = 100 sq ft.

Circle area = pi *r^2 = pi* 5^2

Shaded region area= square area - (circle area)

Shaded area= 100 - 25 pi

shaded area= 21.5 sq ft

So about 22 sq feet
