    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
