Why Is Pi Infinite?

Pi is a number that helps us measure circles, like the ones on your pizza. But pi isn’t just a regular number, it goes on forever, and no one has found the end of it yet. It’s kind of like a never-ending story where every page has more numbers to read.

Examples

You draw a circle on paper, measure around it and across it, the ratio is pi, and you can keep dividing forever!
Your birthday cake has a circular shape. If you wanted to know how much frosting is needed for the top of it, you’d use pi to help you out.
A pizza that's twice as big in diameter covers four times as much space, because pi is hiding behind the math.
