formula of a circle

In this blog we are going to discuss about formula of a circle.
See this link to find out radius of a circle.
The circle is the one of  geometry figure. Circle is two-dimensional shape. Circles are consisting of some credibility in a even that are centermost from a accustomed point alleged the center. The accepted distance of the circle of a point from circle centermost is alleged its radius or artlessly r. the agreement pi and r is mainly acclimated for in circle formulas.
Find area of a circle::

The area of circle is [pi] r 2

The pi value is [22/7] or 3.14

Here r is radius of circle. Value of 4.5 cm

The solution is

Area = [pi] r 2

Area = 3.14 * 4.5 * 4.5

Multiply all the terms

Area of circle is = 3.14 * 20.25

Area = 63.585 cm squared or cm
