Find the area of a circle given C equals four pi give your answer in terms of /n

When given the circumference of a circle (C), we can use the formula for circumference to find the radius (r) of the circle:

C = 2 * π * r
4π = 2 * π * r
r = 2

Once we have the radius, we can use the formula for the area of a circle to find the area (A):

A = π * r^2
A = π * 2^2
A = 4π

Therefore, the area of the circle is 4π, given C = 4π.
