This is a C# Program to calculate area and volume of a cone.

This C# Program Calculates Area and Volume of a Cone.

Here radius and height of the cone is obtained from the user and the surface area and its volume its calculated.

Here is source code of the C# Program to Calculate Area and Volume of a Cone. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

/* * C# Program to Calculate Area and Volume of a Cone */ using System; using System.IO; class program { public static void Main() { double r, h, surface_area, volume; double PI = 3.14; Console.WriteLine("Enter the Radius and Height of a cone : "); r = Convert.ToDouble(Console.ReadLine()); h = Convert.ToDouble(Console.ReadLine()); surface_area = PI * r * (r + Math.Sqrt(r * r + h * h)); volume = (1.0 / 3) * PI * r * r * h; Console.WriteLine("Surface Area of cone is : {0} ", surface_area); Console.WriteLine("Volume of Cone is : {0}", volume); Console.Read(); } }

In this C# program, library function defined in <math.h> header file is used. We are reading the radius and height of a cone using ‘r’ and ‘h’ variable respectively. To compute the area and volume of a triangle the formula are used

Surface_area = 2 * Pi * r * (r + h),

Volume = Pi * r * r * h

Where Pi = 22/7.

Enter the Radius and Height of a cone : 3 3 Surface Area of cone is : 68.2256752726637 Volume of Cone is : 28.26
