A circle is the set of all points in a plane that are a given distance from a given point in that plane. The given point is the center of the circle. A radius of a circle is a segment that has one endpoint at the center of the circle and the other endpoint on the circle.
If a circle has an area A square units and a radius of r units,
then the formula would be A=πr2
