A grain silo has the shape of a right circular cylinder surmounted by a hemisphere. If the silo is to have a volume of 498π 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 πr^2h + 2 3 πr^3, and the surface area (including the floor) is π(3r^2 + 2rh). (Round your answers to one decimal place.) r= ft h= ft
