        r = Convert.ToDouble(Console.ReadLine());
        h = Convert.ToDouble(Console.ReadLine());
        surface_area = PI * r * (r + Math.Sqrt(r * r + h * h));
        volume = (1.0 / 3) * PI * r * r * h;
        Console.WriteLine("Surface Area of cone is : {0} ", surface_area);
        Console.WriteLine("Volume of Cone is : {0}", volume);
        Console.Read();
    }
}
Program Explanation

In this C# program, library function defined in <math.h> header file is used. We are reading the radius and height of a cone using ‘r’ and ‘h’ variable respectively. To compute the area and volume of a triangle the formula are used

Surface_area = 2 * Pi * r * (r + h),

Volume = Pi * r * r * h

Where Pi = 22/7.
