find and determine the value of (and hence, the value of ) that maximizes .
I really need some help to solve this problem:
A factory are going to to make cylindershaped cans. The sum of the diameter and height are 80 cm. which measures gives the greatest volume?
Im sorry for it's a repost but it'll be handed in on a couple of eight hours of beaty sleep. So it would mean the world to me if someone could help me.
