I shall answer the first two.

A.) The same since the area of the sheet is the same in both the cylinders the surface area is the same.

B.)The volume of the short cylinder is,

V=(1/3)pi(5.5)^2(8.5)=269.26 cubic inches

The volume of the tall cyclinder is,

V=(1/3)pi(4.25)^2(11)=208.065 cubic inches

Thus the shorter has more volume.
