Imagine you have a round pizza. If you measure the distance around it, that’s circumference, and then divide it by how wide it is, that’s the diameter, like from one side to the other, you always get the same number, no matter how big or small your pizza is. That number is called π (pi), which is about 3.14. It shows up in everything from wheels to waves because circles are everywhere.
Examples
- A pizza has a circumference of about 31.4 inches, and its diameter is 10 inches, dividing them gives you π.
