Write the following code in c #,3. Write a method call CalculateAreaOfCircle(). This method will prompt the user for the radius of a circle and then calculate and display the area.[A = πr2]. Call the CalculateAreaOfCircle() method twice from the same Main() method as in question 1. Use Math.Pi for the value of π

Sure, here's the code in C#:

using System;

class Program
{
    static void Main()
    {
        // Call the CalculateAreaOfCircle method twice
        CalculateAreaOfCircle();
        CalculateAreaOfCircle();
    }

    static void CalculateAreaOfCircle()
    {
        Console.Write("Enter the radius of a circle: ");
        double radius = double.Parse(Console.ReadLine());

        double area = Math.PI * radius * radius;

        Console.WriteLine($"The area of the circle is: {area}");
    }
}

This code defines a `Program` class with two methods: `Main` and `CalculateAreaOfCircle`. In the `Main` method, we call `CalculateAreaOfCircle` twice.

The `CalculateAreaOfCircle` method prompts the user for the radius of a circle, reads in the input using `Console.ReadLine`, calculates the area using the formula `A = πr^2`, and then displays the result using `Console.WriteLine`.

The `Math.PI` constant is used to represent the value of `π` in the calculation.
