I got D with what you put in your last comment.

A diameter of 64 is a radius of 32.

 The distance around half a circle is 1/2 of its circumference.

 Crank this out: (1/2) * 2 * pi * (32)

 Post what you get and we can compare answers.

Note: Circumference = 2 * pi*r where r is the radius.
