A circle is a shape where every point along the edge is equidistant from a point at the center. The distance from the center to the edge is called the radius. The distance across the widest point of a circle is called the diameter, and it is always equal to the radius x 2. The distance around the circle is called the circumference, and is equal to the diameter x 2 x pi (3.14 and so on). The area of the circle is equal to the radius squared (multiplied by itself) x pi.
