Question

A right cylinder and an oblique cylinder have the same radius and the same height. How do the volumes of the two cylinders compare?
A.
The volumes are the same, based on Cavalieri's principle.
B.
The volumes are not the same, because Cavalieri's principle does not apply to oblique solids.
C.
The volumes are not the same, because the two solids do not have the same cross-sectional area at every level parallel to the bases.
D.
The volumes are not the same, because an oblique solid has less volume thanits corresponding right solid with the same height.
