Pi have been studied for over 10 centuries!!!

"...although many mathematicians have tried to find it, no repeating pattern for pi has been discovered..." (http://mathforum.org/dr.math/faq/faq.pi.html).

No. Pi was discovered by mathematicians to measure the circle.
Pi was not invented but it was discovered by ancient mathematicians that the circumference of any circle when divided by its diameter is always equal to pi.
William Jones in 1706
It's basically 22/7 as a fraction
Pumpkin pi a ll mode
This is because pi is 22/7 and no one can change the fact and people or mathematicians converted the fraction into decimal which is later estimated as 3.14 or then the decimal will be so long and there will never be an end.
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.
