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

Answer 1

First, we need to find the radius of the circle using the formula for circumference:

C = 2πr
4π = 2πr
r = 2

Now 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.
