[ ] Choice 3: pi = 3 [needs legislature of Indiana approval] Attempts to legislate pi are always questionable, and when you ask a majority of uninformed voters[3] to choose between items, it's natural for the compromise to win, and not unheard of for it to end up "3".
Funny thing is that pi=3 was the "official" value taught in Japanese schools in the last few years when pupils were introduced to the value, since it was considered that decimal numbers were too complex... This has been reverted last year if I remember well.
