Hi there!

We can find the circumference of a circle by using the following formula:
circumference = pi × diameter

In this particular situation the diameter of the circle equals the distance AB. Therefore the diameter is 14 inches.

We can now plug this in into our formula to find our answer.
circumference = pi × 14 inches = 14pi inches.

The answer is A.
