Derra Lusk

Circumference, diameter and radii are measured in linear units, such as inches and centimeters.  A circle has many different radii and many different diameters, each passing through the center.  A real-life example of a raduis is the spoke of a  bicycle wheel.  A 9 inch pizza is an example of a diameter:  When one makes the first cut to slice a round pizza pie in half, this cut is the diameter of the pizza.  So a 9 inch pizza has a 9 inch diameter.
