A semicircle is half a circle, so its area is half that of a circle:
radius = 1/2 diameter = 22 ÷ 2 = 11
area = 1/2πr2
= 1/2π112
~= 190 sq in

How do you find the area of a semi-circle if you know the diameter?
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.
How many inches do you need to cover the semi circle given below if its diameter is 28 inches?
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).
What is the approximate area of a circle with a diameter of 14 inches?
About 153.86 square in. To find out the area of a circle do: r^2*pi.
