## Area of Circle

A line forming a closed loop, every point on which is a fixed distance from a center point is called circle.

A circle is a simple shape of Euclidean geometry that is the set of all points in a plane that are a given distance from a given point, the center. The distance between any of the points and the center is called the radius. It can also be defined as the locus of a point equidistant from a fixed point.

The area enclosed by a circle is equal to that of a triangle whose base has the length of the circle circumference and whose height equals the circles radius, which comes to (pi) multiplied by the radius squared.

## $$\Pi {r}^{2}$$

Here r=radius of circle.
