Pi is the number that shows how many times a circle’s edge fits around its width.

Imagine you have a round pizza. If you measure all the way around the outside of the pizza, that's the circumference. Now, if you measure across the middle of the pizza from one side to the other, that's the diameter. Pi is like a special ruler that tells you how many times the diameter fits into the circumference.

Let’s say your pizza has a diameter of 10 inches. If you roll out a piece of string around the edge of the pizza, and then measure how long it is, that's the circumference. You’ll find out that the length of the string is about 31.4 inches.

Now do some simple math: divide the circumference (31.4) by the diameter (10), and you get about 3.14, which is Pi!

You can try this with any round object, like a plate or a wheel. No matter how big or small it is, when you divide its circumference by its diameter, you always end up close to 3.14.

So Pi helps us understand circles, and pizzas! 🍕
