Why Do Numbers Like π Appear Everywhere?

π is a special number that shows up when you measure round things. Like the distance around a pizza compared to its width, it always ends up being about 3.14, no matter how big or small the pizza is. That’s why π shows up everywhere we see circles, like wheels, planets, and even your head!
