Attributes of Circles

This video can run circles around other videos about circles. Sir Cumference, of Round Table fame, explains all the properties of… well, circles. Whether you're looking for how the radius relates to the diameter or how to deal with pi (when you’re not eating it, that is), this video covers the basic attributes of our circular friends. Our rotund knight even hits on area and perimeter, too. En garde!
