The formula for the circumference of a circle is C = 2πr, where r is the radius. Given that C = 4π, we can solve for the radius:
4π = 2πr
4 = 2r
r = 2
Now that we know the radius is 2, 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.
Find the area of a circle given C=4π . Give your answer in terms of π .
