This lesson offers an interesting, hands-on experience for middle school students studying cylinders. Students will create cylinders, and measure and compare their volumes.

This personal site from Math2.org gives formulas for the area, volumes and surface areas of various shapes. Also provides diagrams.

This question and answer site deals with the derivation of the formula for the surface area for the frustum of a right circular cone.

This site from the Math Forum provides the formulas for finding the area and volume of a sphere.

This online calculator will calculate the various properties of a capsule given any 2 known variables including radius r, side length a, surface area S, volume V and circumference C.

MathWorld gives a simple and complex definition of a hemisphere. The formula for the volume of a hemisphere is also given.

This MathWorld site defines many different types of prisms. It gives the formulas for the volume and area of a prism the site has many illustrations [Requires Java.]

This site from MathWorld is a good site explaining Green's Theorem. The information presented is fairly brief but very helpful, and several formulas and examples are given along with links to additional information.

Students learn about a sphere. The resource consists of facts, formulas, images, and definitions. An animation demonstrates how the sphere can contain the greatest volume for a fixed surface area.

In this exercise, students practice volume word problems with cones, cylinders, and spheres. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

This is a site for students and teachers of all grade levels. If you are looking for math tables, general information about math topics, or you would like to ask a question, this is the site to visit.

This InterMath site gives a decription of a hemisphere along with a visual representation. Be sure to use the links to related terms, everyday examples, challenging problems, more information, and the interactive checkpoint involving...
