Pi is an irrational number that does not have a specific value that can be shown. Often, the value is rounded to 3.14 or shown as the fraction 22/7. Outside of mathematics, pi is also used in physics for calculating measurements such as angular velocity. Pi is also necessary when converting between degrees and radians, as one radian is equal to pi/180 degrees.
