And I only know up to 3.14592 off by heart
5. You pi-eaters!

7. 22, apparently. We had a Pi day competition at school for the Year 7s, they had a week to learn as many decimal places of pi as they could and the winner learnt it to about 120 places. The girl who came second learnt it to about 100 places.
8. 3.14 is as far as I can say confidently.

I find it strange the way people remember it to say 3.1415 when the next number in 9.
9. i could do 25 which i will prove now:

3.1415926535897932384626433
10. 3.14
11. A professor of mine once told me that he had memorized the decimal expansion of pi to 100 places when he was younger. He followed by stating that it was arguably the most useless and meaningless exercise he had ever taken part in.

That was poor. Really poor.

Wikipedia rocks.

Just out of interest, if my calculator shows pi as 3.14159265, is that the value it calculates with or does it use a higher accuracy?
Virtually always my answers get left in terms of pi anyway
14. 3.1415926 straight from my mind without looking it up. The mnemonic is 'Can I have a large container of coffee?' Count the letters of each word.

If you want to see if it uses a more accuracy version of pi just do, (pi - 3.14159265) and it will give you the rest in standard form.

Indeed.... 22/7 does not equal pi, heh

Pi day is better. March 14th
17. 3.141592653

I challenge anyone to remember it to this many: http://newton.ex.ac.uk/research/qsys...abs/pi/pi6.txt
18. my cat's called pi.

19. I just tryed to post pi to 10 million decimal places. Surprisingly it crashed my browser.... shame that.

I have it memorised at 10 decimal places (along with e), though i occasionally learn it ato a few more the forget them. It truly is the most useless thing to memorise (except to annoy arts students with).
