Answer: D. The sphere and the cylinder would have the same volume.
Explanation:
Firstly we need to make up a fake set of numbers. Lets say r = 6 and H = 8.
Cylinder formula: V = pi r^2h
Cone formula: V = pi r^2 h/3
Sphere formula: V = 4/3 pi r^3
SO, using the formulas above, the answers come out to:
Cylinder volume = 904.78
Cone volume = 402.12
Sphere volume = 904.78
