Pi = Circumfrence/Diameter
Tau = Circumfrence/Radius
I have noticed a lot of sites, including Khan Academy, in support of tau over pi...
so what do you think?
https://www.scientificamerican.com/article/let-s-use-tau-it-s-easier-than-pi/
However i am still in support of the good ol pi :)
(btw this is my first aops poll) :-D
EDIT: 50 votes!!! :play_ball:

Back in 2023 when I took states the CDR cutoff was 28 (with tiebreaks) and the nats cutoff was 33. Ohio is mid rn. There is like one or two people in middle school who are near jmo level, but competition isn't super intense. ( I made nats in 2023 )
