Question

the circumference of the great circle of a sphere is 12 pi inches. Which of the following expressions can be used to approximate the volume of the sphere?

Answer 1

It would be A because with volume you would have your 12 to the 3rd power then multiply it by pie which is 3.14 then for sphere you would then multiply what ever you got after multiplying 12 to the 3rd power then by 3.14 to the 4/3
