What is the real value of pi?
Are there any interesting facts related to pi?
Yes, there are many interesting facts related to pi. One is that pi has been calculated to trillions of digits, but it still remains an irrational number which means it cannot be expressed as a finite fraction. Another interesting fact is that pi has been studied by mathematicians for thousands of years, with the ancient Babylonians and Egyptians having approximations for pi even before it was formally defined.
