A Quest for Getting Close to Pi

“A bell cannot tell time, but it can be moved in just such a way as to say twelve o’clock – similarly, a man cannot calculate infinite numbers, but he can be moved in just such a way as to say pi.” 

Values of Pi approximations:

1. Simply, 22/7. It will be close to 3.142857.....

2. Cube root of 31

3. 355/113

4. Cube root of  the result obtained by dividing 43.849497 by root 2

5. limit when x tends to (infinity)

pi = n*sin(180/n)

6. pi = 3.14159265358979323846264338327950288419716939937510
