Hi Friend,
Try the following code:
import java.util.*;
class Circumference{
final static double pi=3.14;
public static double circum(double r){
return 2*pi*r;
}
public static void main(String[]args){
Scanner input=new Scanner(System.in);
System.out.println("Enter radius: ");
double r=input.nextDouble();
double circumferenceOfCircle=Circumference.circum(r);
System.out.println("Circumference of Circle: "+circumferenceOfCircle);
}
}
Thanks
