          Truncated Cylinder. the geometric solid produced when a cylinder is cut by a plane that is not parallel to the base.

volume of a truncated right circular cylinder is V = πr² [(h1 + h2)/2] (where 'r' is the radius of the cylinder, 'h1' is the height of the cylinder and the 'h2' is the surplus height after truncate)
