@NJHpro you could say that its irrational, but that doesnt mean it isnt possible. just give the sollution as a multiple of Pi. for example a circle with a radius of 5 would have a circumference of 10*Pi. its irrational but using the short form of pi you can easily right it down. you hand over the problem of defining pi to your teacher or whoever has to correct that shit.

so wait that means in my geometry class i can just say irrational on a circumference test? or not possible?

@mathematicsonline This is true, but that would mean that there is an upper limit to this growth at 3.1416.. however, wouldn't a circle's circumferance be continually increasing untill it "reached" some point N where, beyond which, Epsilon<0 for the Limit of 3.1416

@Tubewaytorpedo You're stupid.

Really didn't understand it in my math books. Thank god there's YouTube..

I can also get pie by driving to Marie Calendars lol
All jokes aside, it was the easiest explanation for pi. I plan to use this video with my future students =)

I have a HUGE quesiton. If Pi is irrational... does that mean that the circumferance of a circle is always growing.. in the sense that pi never ends and is always is always bigger than you can calculate because you can always add one more digit?

@NickMinaj69 Yes there is an infinite number of digits in pi, but that doesn't mean the value of pi increases every time you add a digit. Pi will never be larger than 3.1416 no matter how many digits you calculate the accuracy of pi.
