4. Program to Accept value of Radius and Calculate Area of Circle.

class CalculateCircleAreaExample
{

public static void main(String[] args)
{

int radius = 3;
System.out.println("The radius of the circle is " + radius);

/*
* Area of a circle is pi * r * r where r is a radius of a circle.
*/

// NOTE : use Math.PI constant to get value of pi
double area = Math.PI * radius * radius;

System.out.println("Area of a circle is " + area);
}
}
