Step-by-step explanation:

10-9

141.89526818714 cubic inches

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
