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

1 answer

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

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

Now, we can use the formula for the area of a circle:
A = πr^2
A = π(2)^2
A = 4π

Therefore, the area of the circle is 4π square units.
