Circumference and Diameter Relationship
With a ruler and a piece of string, geometers measure the circumference of a circular object. Tracing and folding it, they find the diameter of the resulting circle so that they can relate it to the circumference. It is recommended that students cut the circles out before folding the paper as to fold them directly in the middle.
