Question

the circumference of a circle is 6π inches. what is the area of the circle? a = πr2 3π in.² 9π in.² 12π in.² 36π in.²

Explanation:

Step1: Find radius from circumference

$C = 2\pi r = 6\pi$, so $r = 3$ inches.

Step2: Calculate area

$A=\pi r^{2}=\pi\times3^{2}=9\pi$ in².

Answer:

$9\pi$ in²
