Why is Pi wrong?

[ludwig]

It should be exactly 3 but it's slightly out. How did that happen?
Could there be somewhere else in the universe where it is 3?

[Marijn]

But you want it longer, don't you. Doh!

[Marijn]

It'd have to go through the middle and poke out a bit. I'll shut up now.

For any given circle of radius r . . .

Measuring directly across from one point along the circumference to the next, r fits precisely 6 times.
Since the diameter is equal to twice the radius, pi (the ratio of the measured circumference to the diameter) equals exactly . . . 6/2 = three!

Now what was so hard about that!

So Pi of a hexagon is 3 hooray we can forget the bendy bits and go to bed

[mibn2cweus]

. . . Forget them? That's where we need them most!

[squarebear]

Handy if it's a hexagon rather than a circle though ;-)

I agree. If you're going to bed there's no way you can forget the bendy bits.
