    volume of sphere = 113.14inches³ or

    36πinces³

    Step-by-step explanation:

    given the radius of a sphere = 3inches

    volume of the sphere = ?

    π = 3.14v 0r 22/7

    recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³

    so,

    volume of sphere = 4/3 πr³

    volume of sphere = 4/3 * 22/7 * (3) ³

    volume of sphere = 4/3 * 22/7 * 27

    volume of sphere = (4 * 22 * 9) / 7

    volume of sphere = 113.14inches³ or 36πinces³
