Question

Determine the shaded area.The shaded area is(Round to two decimal places as needed.)

Answer 1

Given Data:

The radius of the circle is r=9 ft.

The side of the square will be twice the radius of the circle, i.e.a=18 ft.

The area of the shaded region can be determined by substracting the area of circle from the area of square,

`\begin{gathered} A=A_s-A_c \\ =(18ft)^2-(\pi(9ft)^2) \\ =69.53ft^2 \end{gathered}`

Thus, the requried shade area is 69.53 square foot.
