      Circles: radius, diameter, circumference and Pi | Geometry | Khan Academy


      By Khan Academy

      The radius is the distance between the center and any point on the circumference of a circle. The diameter is always twice the radius. The circumference is the perimeter of the circle.

                      Formula for Area of a Circle


                      By Steven Ellis

                      This video shows that pi is equal to the ratio of the area of a circle to the area of a square when the radius of the circle equals the length of the side of the square. This is a view of pi other than the ratio of the circumference to the diameter.
