Where did pi come from?
The babylonians first discovered the ratio compared to the diameter and circumference of a circle. Later, Archimedes(287-212BC) discovered and proved his theory of pi. Pi to 27 decimal places: 3.141592653589793238462643383 The square root of pi (to 30 decimal places) is: 1.772453850905516027298167483314

It is an unending number and millions of digits have been calculated.
Who discovered the concept of pi?
The concept of pi has been known by mathematicians for thousands of years whereas the circumference of a circle divided by its diameter is about 22/7. However, the exact value of pi has never been discovered because it is an irrational number whose decimal places go on for ever and ever.

No, the sum of a repeating decimal and a terminating decimal is never a terminating decimal.
What is the differencce between a terminating and a repeating decimal?
