Pi is used to find the circumference and area of a circle. It is also used to find the volume and surface area of a sphere, cone and cylinder. Pi has applications that go beyond geometry as well, such as statistics and probability.

This proof determines the probability of a needle landing on a line when it is dropped onto a plane containing equally spaced parallel lines. Pi is also prominent in geometric constructions and some formulae involving limits.
