Answer 11

Night. Take it easy.

Answer 12

Well... What is the problem? :)

Answer 13

just needa remember the equation to get to Pi...

Answer 14

You want to approximate \(\pi\)?

Answer 15

yeah. something with division and circles, can't remember the thing for the life of me.

Answer 16

Well pi is the ration between the circumference (perimeter of circle) and the diameter.

Answer 17

ok I think I can do this now, dumb old me forgot about google. heh... but thanks anyways!

Answer 18

This converges to \(\pi\). Start now and in your lifetime you might get it to like 5 decimal places :P\[\pi= 4 \sum_{n=0}^{\infty} \frac{2}{(4n+1)(4n+3)}\]Seriously though \(\pi\) is just \(\pi\). It should always be kept as that unless you want a decimal approximation of something. in that case \(\pi\) is just what you can memorize. You can't compute the decimal value of pi because it is irrational.

Answer 19
