Pi - Wikipedia The number π ( p aɪ ⓘ; spelled out as pi) is a mathematical constant, approximately equal to 3 14159, that is the ratio of a circle's circumference to its diameter It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of
Pi ( π ) - Math is Fun Draw a circle with a diameter (all the way across the circle) of 1 Then the circumference (all the way around the circle) is 3 14159265 a number known as Pi Pi (pronounced like "pie") is often written using the greek symbol π The definition of π is: of a Circle
Pi | Definition, Symbol, Number, Facts | Britannica Pi, in mathematics, is the ratio of the circumference of a circle to its diameter Because pi is irrational (not equal to the ratio of any two whole numbers), its digits do not repeat, and an approximation such as 3 14 or 22 7 is often used for everyday calculations
Pi - Math. net Pi is the ratio of the circumference of a circle to its diameter: Using this relationship, we can determine equation for the circumference of a circle by solving for C: where C is the circumference, d is the diameter, and r is the radius of the circle Another well-known formula that uses pi is the area of a circle
Pi (π) - Math Tools It is defined as the ratio of a circle's circumference to its diameter, and it also has various equivalent definitions It appears in many formulas in all areas of mathematics and physics It is approximately equal to 3 14159 Pi (π) is also a really useful number
