Watch an animated demonstration of finding the volume of a cone and cylinder with the same base and height in this video from KCPT. In the accompanying classroom activity, students estimate the relative volume of a cone and cylinder with the same base and height. They test their estimates by filling the cone and pouring the contents into the cylinder and then use the cylinder volume formula as a basis for predicting the cone volume formula. To get the most from the lesson, students should know the formulas for the area of a circle and volume of a cylinder.
