Best Answer

"Not as a decimal or fraction as there are an infinite number of digits."

This is a common and useful answer.

The *correct* answer is that PI is firstly an irrational number that cannot be calculated from any ratio (fraction).

Secondly, PI is a transcendental number that, by the definition of "transcendental", cannot be exactly calculated.

The nest you can do is to apply an infinite convergent series that becomes more and more accurate with more and more decimal places.

No one has ever found the exact value of pi because it is an irrational number that can't be expressed as a fraction and its value has been calculated to more than two trillion digits yet still not found exactly.

Lots of people did this; the accuracy increased over time.

tan(pi/3)= sqrt(3)

You either keep it as "89 pi" to have the exact value, or you take the desired number of decimals for pi (depending on the desired precision), for example 3.14, or 3.1416, and then multiply.

3.1415926536 is to 10 places but not exact. The only exact value of pi is pi itself. So any exact answer involving pi would include pi in the answer.

No, because pi has no exact value, it is neverending. You can get close by using 3.14, but never will you get it exactly right. Up to date, about 4 trillion digits have been calculated.

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).

Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.

The Egyptians calculated pi to be 3.16.

The circumference of any circle when divided by its diameter has the exact value 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?

They gave it a value of about 3 but even today we do not know the exact value of pi
