Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course.

The Math.PI is a property in JavaScript which is simply used to find the value of Pi i.e, in symbolic form Π 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 a mathematics problem.

Syntax:

`Math.PI`

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

Below example illustrates the Math PI property in JavaScript.

Example: Here simply value of PI i.e, Π is shown as output.

```Input : Math.PI
Output : 3.141592653589793```

More codes for the above property are as follows:

Program 1:Value of PI i.e, Π can be printed as in the form of function as shown below.

## Javascript

 ``

Output:

`3.141592653589793`

Program 2: Here we consider Math.PI as a function but in actual it is a property that is why error as output is being shown.

## Javascript

 ``

Output:

`Error: Math.PI is not a function`

Program 3: 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

Output:

`78.53981633974483`
