Area of a Circle Using a Function in C#

 A program that will ask the user to give the radius of the circle and then the program will compute the area of the circle using a function in C# programming language.

Program Listing

using System;

class Program {
    static double Area_Solve(double radius) {
        const double PI = 3.14159; // defining the value of pi
        return PI * radius * radius; // calculating the area of the circle
    }

    static void Main(string[] args) {
        double radius, area;
 
        Console.WriteLine();
        Console.WriteLine("\tArea of a Circle Using a Function in C#");
        Console.WriteLine();
        Console.Write("\tGive the radius of the circle: ");
        radius = Convert.ToDouble(Console.ReadLine());

        // calling the function to calculate the area of the circle
        area =  Area_Solve(radius);
        
        
        Console.WriteLine();
       Console.WriteLine("\tThe area of the circle with radius {0} is {1:0.00}."
       , radius, area);
        Console.WriteLine();
        Console.WriteLine("\tEnd of Program");
        Console.WriteLine();
        
    }
