Hello Friend,

Try the following code:

import java.util.*;
class CalculateCylinderArea 
{
    public static void main(String[] args) 
    {
        double pi=3.14;
        Scanner input=new Scanner(System.in);
        System.out.print("Enter Radius: ");
        double r=input.nextDouble();

        System.out.print("Enter Height: ");
        double h=input.nextDouble();

        double v1=2*pi*r*r;
        double v2=2*pi*r*h;

        double surfaceArea=v1+v2;
        System.out.println("Surface Area of Cylinder: "+surfaceArea);
       }
}

Thanks
