The formula for the area, A A, of a circle is built around its radius. You find the area of a semicircle by plugging the given radius of the semicircle into the area of a semicircle formula. The area formula is: A = πr2 2 A = π r 2 2
A semicircle has a circumference of 10 Radius = 10 ÷ π = 10 ÷ 3.14159 = 3.183102 Area = (π x 3.183102 2) ÷ 2 Area = (3.14159 x 10.13214) ÷ 2 Area = 31.83103 ÷ 2 Area = 15.9155
