Answer

The
value of pi
to 5 decimal places is 3.14159. Pi is an irrational number, so it cannot be expressed as an exact fraction and its decimal representation has no end.

The Greek letter pi was first used to represent the ratio of the circumference of a circle to its diameter in 1709 by mathematician William Jones.
