Submitted by Nidhi, on April 24, 2021

Here, we will learn about the PI property of Math class. This property is used to return the value of PI.

Syntax:

    double Math.PI;

Return value:

It returns the value of PI constant.

Program:

The source code to demonstrate the use of PI property of Math class (In this program, we are going to calculate the area of circle using the PI property.) is given below. The given program is compiled and executed successfully.

using System;

class Sample
{
    //Entry point of Program
    static public void Main()
    {
        double AreaOfCircle = 0.0;
        int radius = 12;

        AreaOfCircle = (Math.PI * radius * radius);

        System.Console.WriteLine("Area of Circle: "+AreaOfCircle);
    }
}

Output:

Area of Circle: 452.38934211693
