C

Radius of the circle = 8.pi/(2.pi)

Radius =4

Hence area = pi.4^2
=16.pi

(A) 4π
(B) 8π
(C) 16π
(D) 32π
(E) 64π

Circumference = 2πr
2πr = 8π
r = 4

Area = \(πr^2 = 16π\)

Answer C

Since the circumference of a circle is given by C = 2πr, we can create the equation:

8π = 2πr

4 = r

So the area is π x 4^2 = 16π.

Answer: C
