Adam is designing a cat food can. It will be the shape of a circular cylinder and it will enclose a volume of 20 3 i n 3 . The bottom and top lids of the can will be made from material that costs $0.10 per 2 i n 2 and the sides will be made from a material that costs $0.06 per 2 i n 2 . What dimensions of the can will minimize the cost? What is the minimum cost?

Surface area of the circular top and bottom lids: ^2

Surface area of the sides of the can: 2

where r = radius and h = height of the can
