Formula based program

Formula #2 (Perimeter and area of circle)

Enter radius: 5

Perimeter of circle: 31.4159265358979

Area of circle: 78.5398163397448

The program for the formula is written in C# programming language and will accept a number as radius. Based on the formula it will find out the perimeter and area of circle.

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code these formula.

Practical Implementation:

using System;

namespace patternProblem.Formula

{

    class Formula2     //area and perimeter of circle

    {

        static void Main(string[] args)

        {

            Console.Write("Enter radius: ");

            double radius = Convert.ToDouble(Console.ReadLine());

            double area = 0.0, perimeter=0.0;

            perimeter = 2* Math.PI * radius;

            area = Math.PI * (Math.Pow(radius, 2));

            Console.WriteLine("Perimeter of circle: {0}", perimeter);

            Console.WriteLine("Area of circle: {0}", area);

            Console.ReadKey();

        }

    }

}

Output:

The input radius here is 7. So, based on the circle formula. The output is shown below:

Enter radius: 7

Perimeter of circle: 43.9822971502571

Area of circle: 153.9380400259
