For a circle with a specified radius (r), pi can be used to calculate its area (πr2) and circumference (2πr). Based on this relationship, pi can also be used to determine the volume and surface area of cones and cylinders, and to calculate related phenomena such as liquid flow rates and frequency of pendulum cycles.

In statistics, pi is used in the formula to calculate the probability density function for the normal distribution, and the variance of the logistic and extreme value distributions.
