Question
A cylinder shaped can needs to be constructed to hold 250 cubic centimeters of soup.
The material for the sides of the can costs 0.02 cents per square centimeter. The
material for the top and bottom of the can need to be thicker, and costs 0.08 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
= T
Area of the sides: A = 2arh
Area of the top/bottom: A
To minimize the cost of the can:
Radius of the can:
Height of the can:
Minimum cost:
cents
