Volumes of Cylinders and Cones

If you can find the volume of a cylinder, finding the volume of a cone is just one extra little step. Scholars determine the formula for the volume of a cylinder by applying the concept of the area of the base times height. They then use rice or water with models of cylinders and cones to identify that the volume of a cone is 1/3 the volume of a cylinder.
