Why Does π Appear Everywhere in Nature?

Imagine you're drawing a circle with chalk on the ground. The distance around it is pi times the distance across it, that’s how we know π = circumference ÷ diameter. No matter how big or small your circle is, this works every time! So why does π pop up in so many places? Well, circles are everywhere: wheels, pizzas, and even the waves in a pond. That’s where pi hides!
