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

Answer 1

To find the area of a circle given the circumference, we can use the formula:

C = 2πr

Given that C = 4π, we can solve for r:

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 = 4π

Therefore, the area of the circle is 4π.
