Writing Equations from Word Problems : Cost of Materials for Making a Cylindrical Can
A cylindricial can has a volume of 400*3.14cm^3. the material for the top and the bottom cost 2 cents per square centimeter. The material for the vertical surface costs 1 cents per square centimeter.
a. Express the cost C of the materials used to make the can as a function of the radius r.
b. Find the minimum cost.
The cost for making a cylindrical can is minimized.
