Question

radius: 12 in
circumference:

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 12$ in into the formula:
$C = 2\pi \times 12$

Step3: Calculate the result

Simplify the expression:
$C = 24\pi$ in (or approximately $75.36$ in if using $\pi \approx 3.14$)

Answer:

$24\pi$ inches (or approximately 75.36 inches)
