Dec 10 2025 Pi in mathematics is theratio 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 The number pa spelled out as pi is a mathematical constant approximately equal to3.14159 that is the ratio of a circle s circumference to its diameter 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 asPi.Pi pronounced like pie is often written using the greek symbol
The definition ofis of a Circle Pi often represented by the lower case Greek letter one of the most well known mathematical constants is theratio of a circles circumference to its diameter May 17 1999 Succinctly piwhich is written as the Greek letter for p or is theratio of the circumference of any circle to the diameter of that circle Pi is anirrational number which means you cant write it as a simple fraction
Its decimal form goes on forever and never settles into a repeating pattern. No matter how far you go the digits keep coming. We use the Greek letter to represent it \ \pi\ is the ratio between a circle s circumference and diameter
That is \ [\dfrac {\text {circumference}} {\text {diameter}}=\pi.\] \ \pi\ is a fundamental constant in mathematics especially in geometry trigonometry and calculus Piis a name given to the ratio of the circumference of a circle to the diameter
That means for any circle you can divide the circumference the distance around the circle by the diameter and always get exactly the same number Piis a constant value. That is the ratio of the circumference to the diameter is the same for all circles
The drawing below shows the circumference of a circle that has been straightened out. It is a little more than three diameters in length Piis an irrational number Pi Pi is one of the most famous constants in mathematics representing the ratio of a circle s circumference to its diameter
