A can in the shape of a right circular cylinder is required to have a volume of 500 cubic centimeters. The top and bottom are made of material that costs 5¢per square centimeter, while the sides are made of material that costs 4¢per square centimeter. (a) Express the total cost C of the material as a function of the radius r of the cylinder. Find the right side of the equation. Express the cost in dollars. C(r)= (Simplify. Type an exact answer in terms of π.) (b) Graph C=C(r)using your graphing utility. Which graph shown below is the graph of C(r), as displayed on a graphing utility? All four graphs use the following limits: [0, 12]by[0, 60], Xscl=1, Yscl=8. For what value of r is the cost C a minimum? r=__ centimeters (Round your answer to two decimal places.)

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
