Question

write a program which calculates the surface area and volume of a cylinder

Answer 1

import java.util.*;

class cylinder

{public static void main()

{

  Scanner sc= new Scanner(System.in);

System.out.println("Enter the radius of the cylinder");

double r=sc.nextDouble();

System.out.println("Enter the height of the cylinder");

double h=sc.nextDouble();

double pi=3.14;

double v=pi*r*r*h;

double sa=(2*pi*r*h)+(2*pi*r*r);

System.out.println("The volume of the cylinder is "+v);

System.out.println("The surface area of the cylinder is "+sa);

}

}
