Hmmm. I think you may have encountered a problem in series and sequences. I seem to remember sqrt(pi) being expressible as a series.

Pi is an irrational (and transcendental) number, so it is impossible to express it as a fraction or a finite decimal. If you can be more specific as to what you're looking for . . .

My ex-mother in law was irrational and into transcendental medidation. Does that mean she was a Pi? I always thought she was a witch.

If I remember correctly, functions can be transcendental, not numbers.
