We need to design a cylindrical can with radius r and height h. The top and bottom must be made of cooper, which will cost 2 cents/in2. The curved side is to be made of aluminum, which will cost 1 cent/in2. We seek the dimensions that will maximize the volume of the can. The only constraint is that the total cost of the can is to becents.
