What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Using an engaging approach, this lesson requires students to record the volume of cylinders as a function of the radius. Students will construct and measure the volume of several cylinders and then begin comparing these shapes.

This site uses calculus to explain how the formulas for finding the volume of a sphere and a pyramid were derived.

The tutorial examines the area between two curves and the volume of a solid of revolution. The class notes are available in pdf format.

This activity allows the user to find the volume and surface area of various functions as they are rotated around axes. This applet can be used to practice finding integrals using the disk and washer methods of calculating volume.

This site from the Drexel University is a detailed explanation of area and volume for those who have trouble with the concept and need an explanation of how they are related and their differences, and other basic concepts for a clear...
