C#: Calculate and display the surface and volume of a sphere

C# Sharp Basic Data Types: Exercise-8 with Solution

Write a C# Sharp program that takes the radius of a sphere as input and calculates and displays the surface and volume of the sphere.

C# Sharp: Area and volume of a sphere

A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball.

In three dimensions, the volume inside a sphere is derived to be V = 4/3*π*r³ where r is the radius of the sphere

The area of a sphere is A = 4*π*r²

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise8
{
    public static void Main()
    {   
        // Declare variable to store the radius of the sphere
        float r;
        // Define the value of pi
        float pi = 3.1415926535f;

        // Input the radius of the sphere
        Console.Write("Radius: ");
        r = Convert.ToSingle(Console.ReadLine());

        // Calculate and display the surface area of the sphere
        Console.WriteLine("Surface area of the sphere: " + 4 * pi * (r * r));

        // Calculate and display the volume of the sphere
        Console.WriteLine("Volume of the sphere: " + 4f / 3f * pi * (r * r * r));
    }
}

Sample Output:

Radius: 2
