What Is the Secret Behind the Number π?

Imagine you have a round pizza. If you measure the distance around it, that's the circumference. The diameter is how far from one side to the other through the middle. π is like a special number that connects them, if you divide the circumference by the diameter, you always get about 3.14 no matter how big or small the pizza is. People have been using this magic number for thousands of years!
