Afarmer wants to build a new grain silo. the shape of the silo is to be a cylinder with a hemisphere on top, where the radius of the hemisphere is to be the same length as the radius of the base of the cylinder. the farmer would like the height of the silo’s cylinder portion to be 3 times the diameter of the base of the cylinder. what should the radius of the silo be if the silo is to hold 22,500 cubic feet of grain?
