2.27.4.Calculate the radius of a circle given its area using Math function

using System; 

 

class MainClass {    

  public static void Main() {    

    Double r; 

    Double area; 

 

    area = 10.0; 

 

    r = Math.Sqrt(area / 3.1416); 

 

    Console.WriteLine("Radius is " + r); 

  }    

}

Radius is 1.78412203012729
