two prisms DO NOT have the same volume because the cross sections are not the
same. Renee disagrees; she says that it isn't the shape that has to be the same it is the area. Renee thinks
they have the same volume. Who is right and why?

10. Ryllie looks at the two cylinders below and says that the oblique cylinder has less volume because it is at
an angle. The volume for the right cylinder is V = n(g)2(h) and the votumq for the obtique cylinder is V =
zr(alz(sin 73'Xhl because it is at an angle. ts she correct?

11. Jared wants to test out a new theory..... lnstead of having the
cross area sections the same as Cavalieri suggested he wants to half
the radius of one cross section and then double the height to make up
for it. He believes because he divided the radius by 2 but doubleyfh{
height that the volumes should be equal. ls he correct? Explaifi
