Project MATHEMATICS!, California Institute of Technology  
A videotapeandworkbook module that explores a basic topic in high school mathematics in ways that cannot be done at the chalkboard or in a textbook. Although pi is the ratio of circumference to diameter of a circle, it appears in many formulas that have nothing to do with circles. Animated sequences dissect a circular disk of radius r and transform it to a rectangle of base pi*r and altitude r. Animation shows how Archimedes estimated pi using perimeters of approximating polygons.
