    #17 and #23 are both very wrong. #23: 22/7 has only about 0.04025% accuracy. #17: There is an infinite sequence of fractions with each one more accurate than the prior one. Cranking them out via continued fractions is trivial.

    • BunRabit

      you are so true

  • BunRabit

    ugh im foing a stupid assignment and i have to fibd three facts about pi luckily i found this cite:)

  • BunRabit

    number 18 and 24 are the same

    • Bremidon

      …and off by a digit. The first *32* digits do not contain 0.

    • They should replace one of them with a fact that I found myself. I used a program that I wrote to prove my statement: The 5th digit of pi (which is 5) is the only digit which its place inside pi is the value of that place. (5th digit of pi = 5, 23th (and 24th because it has 2 digit) digits of pi =/= 23)

  • Aetzbar

    Logical decision is ..pi is a fixed number
    Imagination says .. Pie changes
    Indeed pie varies from 3.1416 to 3.164
    look…Aetzbar in amazon

  • Axel

    15 is wrong. Look at pi in different bases. It’s obvious that it is a coincidence.
