Get the area of the circle. Use this formula:
Area = [tex] \pi [/tex] * radius^2
We know the radius is 4 yards.
Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24
Now for the square. Double the radius to get the diameter to get the length of the side.
4 * 2 = 8
Formula for finding the area of a square is
Area = side^2
Area = 8^2
Area = 64
And because we only want to shaded portion, we will subtract the area of the circle from the square.
64 - 50.24 = 13.76
So, D) 13.76 square yards is the answer to this question.
