Imagine a circle, like the wheel of your bike. If you measure around the edge (the circumference) and divide it by the distance across the middle (diameter), you always get about 3.14159, no matter how big or small the circle is! That number? It's called pi. Pi helps us understand circles, waves, even the shape of a pizza!
Examples
- You measure around a pizza, divide by its diameter, you get pi!
- If your bike wheel has a diameter of 2 feet, the distance around it is about 6.28 feet because that’s π × 2.
- A round swimming pool with a diameter of 10 meters has a circumference of roughly 31.4 meters.
