static void Main(string[] args)
{
double area, raio , pi;
pi = 3.14159;
raio = Convert.ToDouble(Console.ReadLine());
area = pi * Math.Pow(raio,2);
Console.WriteLine("A={0}\n",area.ToString("N0"));
}
The input value is 2.00 and the expected output value is 12.5664; however, what is coming out is 125,664. How do I fix this?
If you want 4 houses you can not use 0. I did this in a way that avoid breaking the application by typing wrong and using what the language already offers:
using static System.Console;
using static System.Math;
public class Program {
public static void Main(string[] args) {
if (double.TryParse(ReadLine(), out var raio)) WriteLine($"A = {PI * Pow(raio, 2):N4}");
}
}
