# JavaScript Math PI Property

Last Updated : 19 Jun, 2023

The Math.PI is a property in JavaScript that is simply used to find the value of Pi i.e, in symbolic form Î  which is nothing but it is the ratio of the circumference of a circle to its diameter, whose value is approximately 3.141. It is mainly used in mathematics problems.

Syntax:

`Math.PI`

Return values: It simply returns the value of PI i.e, Î

Below is an example of the Math PI Property.

Example: Here simply the value of PI is printed in the console.

## Javascript

 `// Here value of Math.PI is printed.` `console.log(Math.PI);`

Output:

`3.141592653589793`

Example: The value of PI i.e, Î  can be printed in the form of a function as shown below.

## Javascript

 `// function is being called.` `function` `get_Value_of_PI() {` `    ``return` `Math.PI;` `}`   `// function is calling.` `console.log(get_Value_of_PI());`

Output:

`3.141592653589793`

Example: Here we consider Math.PI is a function but in actuality, it is a property which is why the error as output is being shown.

## Javascript

 `// Here we consider Math.PI as a function but` `// in actual it is a property that is why error` `// as output is being shown.` `console.log(Math.PI(12));`

Output:

`Error: Math.PI is not a function`

Example: Whenever we need to find the value of anything related to PI that time we take the help of this property. In mathematics, it needed a lot. Here we are going to find the value of the area of a circle with the given value of its radius.

## Javascript

 `// function is being called with radius 5 as a parameter.` `function` `area_of_circle(radius_of_the_circle) {` `    ``return` `Math.PI * radius_of_the_circle * radius_of_the_circle;` `}`   `// Here area of the circle is 5 unit.` `console.log(area_of_circle(5));`

Output:

`78.53981633974483`
