Find the area of a circle given C = 4π. Give your answer in terms of π. (1 point)
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, C = 4π, so we have:
4π = 2πr
Dividing both sides by 2π, we get:
r = 2
The formula for the area of a circle is A = πr^2, so substituting r = 2, we get:
A = π(2)^2
A = 4π
Therefore, the area of the circle is 4π.
