    = 3052.08 cm^3

    Step-by-step explanation:

    Volume of a sphere is given by

    V = 4/3 pi r^3

    We know the diameter is 18

    d = 2r

    18 = 2r

    Divide each side by 2

    18/2 = 2r/2

    9 = r

    V = 4/3 pi 9^3

    V = 4/3 pi (729)

    V = 972 pi

    Approximating pi by 3.14

    V = 972 (3.14)

    = 3052.08 cm^3
