Java program to find the circumference of a circle

The circumference of a circle is double the product of its radius and the value of PI. Therefore, to calculate the circumference of a circle

  • Get the radius of the circle form the user.
  • Calculate the product
  • Print the final result.


import java.util.Scanner;
public class CircumfrenceOfCircle {
   public static void main(String args[]){
      int radius;
      double circumference;
      Scanner sc = new Scanner(;
      System.out.println("Enter the radius of the circle ::");
      radius = sc.nextInt();
      circumference = Math.PI*2*radius;
      System.out.println("Circumference of the circle is ::"+circumference);


Enter the radius of the circle::
The circumference of the circle is::345.57519189487726
