My thinking is that in this alternate universe where pi=3, circles (with diameter 2 * pi * r) will look like hexagons (which have diameter 2 * 3 * r), so wheels

My thinking is that in this alternate universe where pi=3, circles (with diameter 2 * pi * r) will look like hexagons (which have diameter 2 * 3 * r), so wheels would have to be hexagonal.
