How to calculate the surface area of cylinder in C#

Answer 1

using System;

class Program
{
    static void Main() {
        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);
 
        Console.WriteLine("Cylinder Surface Area = " + cylinder_surface_area1);
        Console.Write("Cylinder Surface Area = " + cylinder_surface_area2);
    }
}



 
 
 
/*
run:
 
Cylinder Surface Area = 942.477796076938
Cylinder Surface Area = 942.477796076938
 
*/
