Agrain silo has the shape of a right circular cylinder surmounted by a hemisphere. if the silo is to have a volume of 505π ft3, determine the radius and height of the silo that requires the least amount of material to build. hint: the volume of the silo is πr2h + 2 3 πr3, and the surface area (including the floor) is π(3r2 + 2rh). (round your answers to one decimal place.)
