Answer:

78.5 in

Step-by-step explanation:

The circumference can be calculated as:


C=2\pi\cdot r

Where r is the radius and π is approximately 3.14.

So, replacing r by 12.5 inches, we get:


\begin{gathered} C=2(3.14)(12.5\text{ in)} \\ C=78.5\text{ in} \end{gathered}

Therefore, the circumference is 78.5 in
