14*9*2=252
Because "the radius and height of the bottom surface of cylinder and cone are equal", that is, the height of cylinder and cone is equal, and the volume of cone is equal to 1/3 of the volume of cylinder with the same height, so
Volume of cylinder = volume of cone *3
The volume of the cone+the volume of the cylinder = 4 times the volume of the cone.
The volume of the cone = 252/4 = 63
Volume of cylinder = 63 * 3 = 189.
