A cone is filled with water. Two solid spheres are placed in the cone as shown in the diagram and the water spills out. (The spheres are touching each other, each sphere touches the cone all of the way around, and the top of the top sphere is at the same level as that of the top of the cone.) The larger sphere has radius twice that of the smaller sphere. If the volume of the water remaining in the cone is 2016 π, then what is the measure of radius of the smaller sphere?
