ANSWER

EXPLANATION

The circumference of a circle is calculated using the formula:

$C=2\pi \: r$

From the question, the radius of the circle is 10 inches.

We substitute the radius into the formula to get:

$C=2\pi * 10$

Let us multiply out to get:

$C=20 \pi \: in$

The question required that we leave the answer in terms of π.

The correct choice is C.
