No. Pi is not a rational number so it cannot be expressed as a ratio of two integers. In fact, you cannot express its exact value.
22 divided by 7 * * * * * That is an APPROXIMATE value of pi. The exact value cannot be calculated since pi is a transcendental number - a special kind of irrational number. It has an infinite decimal representation with no recurring pattern. That would be true in any base - binary, octal, or another base (other than pi itself, or a power of pi).
If the value of pi is the circumference of any circle divided by its diameter then what is the true exact value of pi? Why is it that the exact area of a circle can never be found?
Because 22/7 is the approximate value of pi as a fraction but the exact value of pi has never been determined.
3.14 There is no exact value of pi. It goes on forever. But if you round it, it would be 3.14159265. An estimate of pi is 22/7, or 3 and 1/7. Like said earlier there is no exact value but if you are dealing with fractions use 22/7 but is you are sing decimals use 3.14 or the pi key on your calculator
