Its not pi. Its only a three significant digit approximation of pi. Or its just a rational number which happens to be near pi.
In any case, if you used that as pi, your solution would only be accurate to three significant digits.

It is NOT really pi, but pi = 3.14 is used to simplify the calculations. Another approximation is 22/7.

This is from wikipedia.org:
Pi or Ï is the ratio of a circle's circumference to its diameter in Euclidean geometry, approximately 3.14159. Pi is a mathematical constant and a transcendental (and therefore irrational) real number, with many uses in mathematics, physics, and engineering. It is also known as Archimedes' constant (not to be confused with an Archimedes number) and as Ludolph's number.

3.14 is a example of a number written in demical form. It is also part of the circle formula this number is rounded It is called Pi.

3.14 = 22 / 7 = Ï

It's called "pi".
It's the ratio of the area of a circle to the square of its radius.
It actually has a lot more significant figures (3.141592654)
