Question

the radius of a circle is 12 in. find its circumference in terms of $pi$. answer attempt 1 out of 2 $c = square$ in

Explanation:

Step1: Recall circumference formula

$C = 2\pi r$

Step2: Substitute radius value

Given $r = 12$ in, so $C=2\pi\times12$

Step3: Simplify the expression

$C = 24\pi$

Answer:

$24\pi$ in
