The circumference of a circle is 6π inches. what is the area of the circle?

alternative text
a. 3π in.2
b. 9π in.2
c. 12π in.2
d. 36π in.2

To determine the area of the circle, we need to first calculate the radius of the circle. We can do this from the given circumference. The circumference has a formula of C = 2πr. We do as follows:

C = 2πr
6π = 2πr
r = 3

Therefore, area would be,

A = πr²
A = π(3)² = 9π

Option B is the correct answer.
