    The volume of the cone is 129.4 in³

    Step-by-step explanation:

    First of all to solve this problem we have to know the formula to calculate the volume of a cone

    v = volume

    r = radius = 2.9 in

    h = height = 14.7 in

    π = 3.14

    v = 1/3 * π * r² * h

    we replace with the known values

    v = 1/3 * 3.14 * (2.9in) ² * 14.7in

    v = 1/3 * 3.14 * 8.41in² * 14.7in

    v = 129.396 in³

    Round to the nearest tenth

    v = 129.396 in³ = 129.4 in³

    The volume of the cone is 129.4 in³
