    volume of quarter sphere is 359006 cubic feet

    Explanation:

    Given data

    radius = 70 feet

    to find out

    the volume of quarter sphere size tank

    solution

    we know that volume of sphere is 4/3 * π * r³

    so that when volume of of quarter sphere size

    so The quarter of a sphere has 1 quarter of that volume

    that is volume

    volume will be (1/3 * π * r³)

    now put the value r = 70 feet, and solve it

    volume of quarter sphere = (1/3 * π * r³)

    volume of quarter sphere = (1/3 * π * 70³)

    volume of quarter sphere = 1077020 / 3

    volume of quarter sphere is 359006 cubic feet
