Question

Create a working C# Program that will accept an input and has the following class.

areaCircle – computes the area of the circle

volumeCube – computes the volume of a cube

perimeterTraingle – computes the perimeter of a triangle

surfaceAreaRect – computes the surface area of a rectangle

*You may usePass by Value and/or Pass by Reference

*Using ConsoleApp

Answer 1

Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ShapeApp
{
class Program
{
public static double areaCircle(double radius)
{
return (Math.PI * radius * radius);
}

public static double volumeCube(double a)
{
return a * a * a ;
}

public static double perimeterTriangle(double a, double b, double c)
{
return (a + b + c);
}

public static double surefaceAreaRect(double length, double breadth)
{
return (length * breadth);
}
static void Main(string[] args)
{
//using Math.Round() - to get two decimal places
//area of circle
Console.Write("Enter a radius: ");
double radius = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("The area of a Circle: "+Math.Round(areaCircle(radius),2));

//volume of a cube
Console.Write("\nEnter a length of the edge of a cube: ");
double a= Convert.ToDouble(Console.ReadLine());
Console.WriteLine("The volume of Cube: "+Math.Round(volumeCube(a),2));

//perimeter of a triangle
Console.Write("\nEnter value of Side1: ");
double side1= Convert.ToDouble(Console.ReadLine());
Console.Write("Enter value of Side2: ");
double side2 = Convert.ToDouble(Console.ReadLine());
Console.Write("Enter value of Side3: ");
double side3 = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("The perimeter of a Triangle: "+Math.Round(perimeterTriangle(side1,side2,side3)),2);

//surface area of a rectangle
Console.Write("\nEnter the length of a rectangle: ");
double l = Convert.ToDouble(Console.ReadLine());
Console.Write("Enter the breadth of a rectangle: ");
double w = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("The surface area of a rectangle: "+Math.Round(surefaceAreaRect(l,w)),2);
Console.ReadKey();
}
}
}

Output:
