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.
