Information covering important topics for today's educators and parents. Volumes and surface areas of solid figures. The seven part videotape series uses computer animation, live action video, and graphics to explain geometric shapes and principles. These videos are useful for viewing by individual students as well as a whole class, and are also intended for viewing by the teacher as a learning aid. This video begins by showing a jet in flight and describing how surface area of an aircraft's wings affects the lift of the aircraft.
Animations relate surface area to the sail on a sail boat.
Graphics illustrate the methods needed to calculate the lateral area and surface area for cones and prisms. The detailed presentation of the calculations for the lateral area of a cone is an example of the serious content presented in visual format. Animations also demonstrate informal proofs related to the formulas for the volume of solid geometric shapes. Other animations illustrate the concept of frustum and the meaning of Cavalieri's principle concerning the volume of solids. Three dimensional objects.
