361.1 square feet

Step-by-step explanation:

The area of the smaller circle is:

The area of the larger circle is:

Subtracting the smaller circle from the area of this one, you get 361.1 square feet. Hope this helps!

361.1 ft^2

Step-by-step explanation:

The area of the inner circle is

A = pi r^2 = pi (9)^2 = 81 pi

The area of the outer circle is

A = pi r^2 where r is (9+5) = 14

A = pi (14)^2=196 pi

The shaded area is the outer circle minus the inner circle

196 pi - 81 pi

115 pi

Using 3.14 for pi

115 * 3.14

361.1 ft^2
