Shown in linear notation) Trigonometry π radians = 180 degreesPi or π is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.14159 in the usual decimal notation (see the table for its representation in some other bases). π is one of the most important mathematical and physical constants: many formulae from mathematics, science, and engineering involve π. π is an irrational number, which means that its value cannot be expressed exactly as a fraction m/n, where m and n are integers. Consequently, its decimal representation never ends or repeats. It is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can be equal to its value; proving this was a late achievement in mathematical history and a significant result of 19th century German mathematics. Throughout the history of mathematics, there has been much effort to determine π more accurately and to understand its nature; fascination with the number has even carried over into non-mathematical culture. The Greek letter π, often spelled out pi in text, was adopted for the number from the Greek word for perimeter "περίμετρος", first by William Jones in 1707, and popularized by Leonhard Euler in 1737. The constant is occasionally also referred to as the circular constant, Archimedes' constant (not to be confused with an Archimedes number), or Ludolph's number (from a German mathematician whose efforts to calculate more of its digits became famous).

Have little pis coming out everywhere or something like that. Answered by Shadz - Fri Mar 14 21:14:26 2008 What technological or scientific need exists for pi?
Q. How is pi used in technology or science? Asked by Chandler - Thu Apr 2 13:01:17 2009 - - 1 Answers - 0 Comments A. Pi would be used anytime it is necessary to determine the length of an arc, the measurements of a circle, or even the volume of a cylindrical solid. These measurements could be crucial to the developing or using certain medical equipment. For instance, before inserting a stint into an artery, the doctor would first need to to measure the size of the inside of the artery. This would be determined by using the mathematical formula including pi. Also, if a rocket scientist wanted to determine what the fuel capacity of the cylindrical fuel tank of the rocket is, then he would have to use a mathematical formula using pi to figure it out.
