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
