A solid, in the form of a right circular cone, is mounted on a hemisphere of the same radius. The radius of the hemisphere is 2.1 cm and the height of the cone is 4 cm. The solid is placed in a cylindrical tub full of water in such a way that the whole solid is submerged in water. If the radius of the tub is 5 cm and its height is 9.8 cm, find the volume of water left in the tub.
