Just answered a similar question. Given: Semi-circle bottom is 36 inches The bottom is the diameter of the circle. Radius of the circle is 1/2 of diameter. r = 36incehes / 2 = 18 inches Area of a circle = π r² A = 3.14 * (18in)² A = 3.14 * 324in² A = 1,017.36 in² Area of a semi-circle = Area of a circle ÷ 2 A = 1,017.36 in² ÷ 2 A = 508.68 in²
