Answer 4

I think that we have to apply the principle of Cavalieri for solids

Answer 5

@Michele_Laino We have not learned about that principle but I looked it up and it could apply. What I am having trouble with is creating the proof that the two cross sectional pieces. I tried putting the cone inside the cylinder on a graph and using it as a figure of revolution but am not sure where to go with this and how to relate a cross section to the sphere cross section piece.
