Pi is a special number that helps us measure circles. If you take the distance around a circle and divide it by its width, you always get about 3.14, that's pi! It doesn’t change no matter how big or small the circle is. Pi might look like magic, but it’s just math hiding in plain sight.
Examples
- A pizza with a diameter of 10 inches would have a circumference of about 31.4 inches, which is just pi times its diameter.
