namespace MyApp
{
    class Program
    {
        static void Main(string[] args)
        {
            int iRadius;
            double dCircumference;
            Console.WriteLine("Enter the radius of given circle:");
            iRadius = Convert.ToInt32(Console.ReadLine());
            dCircumference = 2 * 3.14 * iRadius;
            Console.WriteLine("The circumference of a circle is: " + dCircumference);
            Console.ReadLine();
        }    
    }
}
