A can in the shape of a right circular cylinder is required to have a volume of 700 cubic centimeters. The top and bottom are made up of a material that costs 12¢ per square centimeter, while the sides are made of material that costs 5¢ per square centimeter. Find a function that describes the total cost of the material as a function of the radius r of the cylinder.
answers:
C(r) = 0.24πr^2 + (70/r)
C(r) = 0.08πr^2 + (140/r)
C(r) = 0.16πr^2 + (140/r)
C(r) = 0.08πr^2 + (70/r)
