Find the area of the shaded region

Answer 1

The shaded area is equal to
`2500\pi - 1296\pi = 1204\pi.`

Explanation:

The shaded area is equal to the area of the outer circle minus the area of the inner circle.

The area of the outer circle is equal to
`r^2\pi = 50^2\pi = 2500\pi` feet.

The area of the inner circle is equal to
`r^2\pi = 36^2\pi = 1296\pi` feet.

So the area of the shaded area is equal to
`2500\pi - 1296\pi = 1204\pi.`
