Find the area of a circle given C=4π . Give your answer in terms of π .
The formula to find the area of a circle is A = πr^2, where r is the radius of the circle.
Given the circumference C = 4π, we have the formula C = 2πr, where r is the radius of the circle.
Therefore, 4π = 2πr
r = 2
Using r = 2 in the formula for area, we get:
A = π(2)^2
A = π(4)
A = 4π
Therefore, the area of the circle is 4π.
