Please help! :) A stack of DVD'S sit on a base and is covered by an 11cm tall cylindrical lid. What % of the surface area of the lid is covered by the label? Use 3.14 for Pi. (Hint: The lid has not a bottom.) Thank you! :D

I know the answer is about 24%, but, I don't get how to solve it since there is no bottom, help please? ;)
