You plan to build a cylindrical container with no top. The material used for the lateral sides costs $8 per square foot while the material for the bottom costs $3 per square foot. (a) Express the total cost of building the cylinder, C in terms of the cylinder's radius, r, and height, h. c = 161V]: + 31:12 i (b) If the volume of the cylindrical container is 350 cubic feet, express the total cost of building the cylinder, C in terms of the cylinder's radius, .r. C(r) = X
