The formula for the circumference of a circle is C = 2πr.

Given C = 4π, we can solve for the radius by dividing both sides of the equation by 2π:
r = C / 2π
r = 4π / 2π
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.
