The Number Pi*

Outline of a Circle and its Diameter Pi represents the relationship between a circle’s diameter (its width) and its circumference (the distance around the circle).

Equations that use Pi

Area of a Circle

The area of a circle is calculated using Pi and the radius of the circle. This formula inspired the joke “Pies aren’t square, they’re round!”

Volume of a Cylinder

To find the volume of a rectangular prism you calculate length × width × height. In that case, length × width is the area of one side, which is then multiplied by the height of the prism. Similarly, to find the volume of a cylinder, you multiply the area of the base (the area of the circle, which is pi × r²), then multiply that by the height of the cylinder.
