It's a special number in mathematics, it represents the ratio between the circumference(distance around the edge) of a circle and it's diameter(distance from one side to the other directly through the middle). It's used in calculations like Pi x [RxR] (Pi R squared, where R is the radius(distance from the edge to the middle)) to be able to find the area of a circle.
