The decimal representation of pi is an irrational number, meaning it cannot be expressed exactly as a finite decimal or fraction. However, it is commonly approximated as 3.14159. Pi is defined as the ratio of a circle's circumference to its diameter and has infinite, non-repeating decimal digits. Mathematicians and scientists often use the symbol π to represent this fundamental mathematical constant.

Though pi lasts forever and cannot fully be written out, pi is commonly known for its first three numbers: 3.14
pi = about 22/7
pi = 3.1415926535897938.........and so on
pi to 5 decimal places = 3.14159
3*pi = 9.424777961 to nine decimal places.
To have an "entire approximation" in itself is an oxymoron. We have to approximate pi because you cannot express the true value of pi as a decimal. It goes on forever. This is an invalid question. Pi is generally approximated, however, as 22/7 or 3.14.
A non-repeating decimal is a decimal that never repeats itself. For example, pi is a non-repeating decimal.
pi = 3.1415926535897932384626433832795... pi to the tenths = 3.1 pi to the hundredths = 3.14 pi to the thousandths = 3.142 pi to the ten-thousandths = 3.1416 pi to the 10th decimal places = 3.1415926536 etc. ============================
