If the circumference of a circle is 12pi, what is the area?

Given the area of a circle is
12pi.

Then we will calculate the radius using the circumference
formula.

==> C = 2* pi *r = 12
pi

==> r = 12pi/2pi = 6

Now we
will calculate the area of the circle.

==> We know that A=
r^2 * pi

==> A = 6^2 * pi = 36 pi = 113.1 (
approx)

Then the area of the circle whose
circumference 12pi = 36pi = 113.1 square units.
