Question

If the diameter of a men’s basketball is 10 inches and a women’s is 9 inches, what is the approximate difference of their volumes?

Answer 1

Answer:

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
