To What extent do you know pi (π)

Pi is the ratio of the circumference of a circle to its diameter. π is a mathematical constant and is approximated to 3.1459. Pi is a mathematical constant in all circles irrespective of the sizes.

***Pi is an irrational number, which depicts that it cannot be written as the ration of two integers (22/7 being used is to the approximate π).
 
***Pi has an infinite digit to its decimal, meaning it has no end with an infinitely repeating pattern of digits (calculus proves that). 3.141592653589793238462643383279502884197169399375105820974944592307816

***Pi can never be expressed either as square roots or nth roots.
 
***Pi day is March 14 which corresponds with its first three approximated value 3.14 (march’3’ 14^th).
 
***Pi day is also Albert Einstein birthday
 
***To compute π is a stressful test for a computer
 
***As of 2010, the record for calculating pi is to 5 trillion digits.
 
***3.14 backwards look like PIE
 
***In the Greek alphabet, pi (piwas) is the 16^th letter. In the English alphabet, p is also the 16^thletter.
