GeoGebra has a great demo to show that the area of a circle can be shown as any number of pie slices rearranged into a parallelogram. The GeoGebraTube Area of Circles applet was created by Anthony Or, Education Bureau, Hong Kong. Brian made a video to show you how to use the GeoGebra applet or to simply show your math class.
