Circumference C of a circle divided by diameter d of the same circle = pi. Pi is irrational because the properties. Pi = 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 ...

Every person who has ever used the "value" of pi in a calculation has used an approximation.
Archimedes
Pi can be calculated to millions of decimal places and it has not come out even yet, so there is no apparent limit to the number of 1's that will appear in the calculation.
You can only express this exactly by leaving it as is: 22/7 times pi. If you want a decimal approximation, use an approximation of pi, for example. 3.1416, and do the calculation on a calculator.

You take the circumference of a circle and divide it by the diameter.
While there is no fraction form for pi, 22/7 is an approximation of pi that can be used for a rough calculation .
Archimedes
According to most news sources (and Wikipedia), the most accurate calculation of pi currently stands at five trillion digits (5,000,000,000,000 digits!) That's quite a lot.
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number that can't be expressed as an exact fraction.
