    V = 125 pi cm^3

    V = 392.6990817 cm^3

    Step-by-step explanation:

    Volume of a cone = 1/3 pi r^2 h

    The diameter is two times the radius

    d = 2r

    10 = 2r

    10/2 = 2r/2

    5 = r

    V = 1/3 * pi * (5) ^2 * 15

    = 1/3 * pi * 25 * 15

    =125 * pi

    Approximate pi as 3.14

    V = 392.6990817 cm^3
