Find the area of a circle given C = 4 pi. Give your answer in terms of pi.

The formula for the circumference of a circle is given by C = 2πr, where r is the radius of the circle.

Given that C = 4π, we can solve for the radius:
4π = 2πr
r = 2

Now that we have the radius, we can find the area of the circle using the formula A = πr^2:
A = π(2)^2
A = π(4)
A = 4π

Therefore, the area of the circle is 4π.
