A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.

The perimeter of the semicircle is 71.98 inches, approx. The semicircle cannot be covered by any number of inches because an area (in 2-dimensional space) cannot be covered by a length (in 1-dimensional space).
