    We have the following equation:

    V = kr ^ (2) h

    For cylinder A we have:

    251.2 = k * ((4) ^ (2)) * (5)

    Let's clear k:

    k = 251.2 / (((4) ^ (2)) * (5))

    k = 3.14

    For cylinder B we have:

    V = 3.14 * ((3) ^ (2)) * (9)

    V = 254.34 in ^ 3

    Answer:

    the volume of cylinder B is:

    V = 254.34 in ^ 3
