Examples

1. A pizza has a round shape; if you measure around the edge and divide it by its width, you get π.
2. You can see π in the wheels of your bicycle, every time they roll one full turn, the distance traveled is about 3.14 times the wheel's width.
3. Even waves on the ocean follow a pattern involving π, like how ripples spread out from where you drop a stone.
