The material for the top and bottom of the can need to be thicker, and costs 0.05 cents per square centimeter. Find the dimensions for the can that will minimize production cost.
Helpful information:
h : height of can, r : radius of can
Volume of a cylinder: V= pi r^2 h
Area of the sides: A = pi r^2
To minimize the cost of the can:
Radius of the can: =
Height of the can: =
Minimum cost: = cents
