How to calculate the Area of circle inside a square

How to calculate the Area of circle inside a square
From my past experiences and as per knowledge, the short-cut calculation has been developed, called as CBS  FACTOR, the calculation has been shown below……..

Area of circle inside a square =  a X a X CBS FACTOR


Where,
a = Side length of square
CBS FACTOR = 0.785398163397

From above formula, we can calculate Area of circle inside a square instantly with simple multiplication.

For example….
For a 2mt. length of side a square, the Area of circle inside a square has been calculated…
Invert Arch length = a x a x 0.785398163397
             2 x 2  x 0.785398163397->   3.14159 m

The above calculation can be verified using Auto-Cad or any mathematical technique
