Hello!  Hope this helps :)

Here is the equation for Circumference.

Circumference = 2 * pi * radius

The problem gives you the diameter of AB = 14 inches.  The radius of the circle is half of the diameter:

Radius = (1/2) * Diameter

Radius = (1/2) * 14 inches

Radius = 7 inches

Now plug radius into the circumference equation:

Circumference = 2 * pi * radius

Circumference = 2 * pi * 7 inches

Circumference = 14pi inches

(Leave in terms of pi)

Let me know if you have any questions :). Please give me a rating!
