You plan to build a cylindrical container with no top. The material used for the lateral sides costs $6 per square foot while the material for the bottom costs $7 per square foot. (a) Express the surface area of the open cylinder in terms of the cylinder's radius, r, and height, h. S= (b) Express the cost of building the open cylinder in terms of the cylinder's radius, r, and height, h. C= (c) If the volume of the cylindrical container is 400 cubic feet, express the cost of building the cylinder, C in terms of the cylinder's radius, r. C(r) = (d) If the volume of the cylindrical container is V cubic feet, express the cost of building the cylinder, C in terms of the cylinder's radius, r. Note - Your answer will have V in it, but V is a constant here. Use an upper case V. C(r) =
