    Answer:

    1: r = 2.4 cm

    2: V = 57.8765 cm^3

    Step-by-step explanation:

    1:

    The volume of a sphere is given by V = (4/3) * pi * (r^3), being ‘r’ its radius.

    So if the volume is 463.01 cm^3, we have that:

    463.01 = (4/3) * pi * (r^3)

    463.01 * 3 = 4 * 3.14 * r^3

    r^3 = 463.01 * 3 / (4 * 3.14) = 110.59156

    r = 4.8 cm

    2:

    The radius of the second sphere is 4.8/2 = 2.4 cm, so its volume is:

    V = (4/3) * 3.14 * (2.4^3) = 57.8765 cm^3
