How to calculate the surface area of cylinder in Java

Answer 1

public class MyClass {
    public static void main(String args[]) {
        double radius = 6, height = 19;
  
        double cylinder_surface_area1 = (2 * Math.PI * radius * height) + 
                                        (2 * Math.PI * (radius * radius));
  
        double cylinder_surface_area2 = 2 * Math.PI * radius * (radius + height);
  
        System.out.println("Cylinder Surface Area = " + cylinder_surface_area1);
        System.out.println("Cylinder Surface Area = " + cylinder_surface_area2);
    }
}

 
 
  
  
  
/*
run:
  
Cylinder Surface Area = 942.4777960769379
Cylinder Surface Area = 942.4777960769379
