    Step-by-step explanation /

    Vm = Volume of the men's basketball

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

    Vm = (4/3) * pi * (5) ^3 ... diameter = 10 - -> radius = 10/2 = 5

    Vm = 523.598775598299 cubic inches

    Vw = Volume of the women's basketball

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

    Vw = (4/3) * pi * (4.5) ^3 ... diameter = 9 - -> radius = 9/2 = 4.5

    Vw = 381.70350741116 cubic inches

    Difference in volume = Vm - Vw

    Difference in volume = 523.598775598299 - 381.70350741116

    Difference in volume = 141.89526818714 cubic inches

    This result is approximate
