    h = 6units

    Step-by-step explanation:

    The volume of a cylinder

    V = πr^2h

    V = volume

    π = pie

    r = radius

    h = height

    Given:

    V = 24π

    h = 3r

    Insert the values into the formula

    V = πr^2h

    24π = πr^2h

    Since the value of h is not given

    Make h the subject of the formula

    24π = πr^2h

    Divide both sides by πr^2

    24π / πr^2 = πr^2h/πr^2

    24π/πr^2

    π cancels π

    = 24/r^2

    24/r^2 = h

    h = 24/r^2

    Since h = 3r

    3r = 24/r^2

    3r * r^2 = 24

    3r^3 = 24

    Divide both sides by 3

    3r^3/3 = 24/3

    r^3 = 8

    r = 2

    Since r = 2units

    h = 3r

    h = 3 * 2

    = 6units
