We are going to write a program that will calculate the area of ​​a circle. The area enclosed by a circle of radius r is πr², where π (pi) is the constant ratio of the circumference of any circle to its diameter, and r is the radius. The given program declares a constant pi variable with a value of 3.14. Complete the program to take the radius as input, then calculate and output the area of the circle. Sample Input 5 Sample Output 78.5

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace SoloLearn { class Program { static void Main(string[] args) { const double pi = 3.14; double radius; radius =Convert.ToDouble(5); double area; area =pi*radius*radius; Console.WriteLine(area); //your code goes here } } }
