A silo is to be made in the form of a cylinder surmounted by a hemisphere. The cost of construction per square foot of surface area is twice as great for the hemisphere as for the cylinder. Determine the dimensions to be use (in terms of V) if the volume is fixed at V and its cost of construction is to be minimum. Neglect the thickness of the silo and waste in construction.
