Answer:
The shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]
Step-by-step 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 [tex]r^2\pi = 50^2\pi = 2500\pi[/tex] feet.
The area of the inner circle is equal to [tex]r^2\pi = 36^2\pi = 1296\pi[/tex] feet.
So the area of the shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]
