The Main Objective is to use inheritance and method overriding.

Create an object oriented application with C# that computes the area of a circle, and the area and the volume of a sphere of a given Radius. Based on the inheritance concept, create a base class called Circle (The parent class) and a derived class called Sphere (The child class) as shown in Figure 1. The formulas that you require for your calculation are as follows: Area of a circle: Pi Radius^2 Area of a sphere: 4 * Pi * Radius^2 Volume of a sphere: (4/3) * Pi * Radius^3 The output of the application will look like the following: Enter A Radius 3 The area of a circle of Radius 3 The area of a Sphere of Radius 3 Press any key to continue ellipsis
