2. Bina Rajah UML
Draw UML diagram for the class Point and class Circle as described below.
A base class named Point consisting of x and y data members representing point coordinates. From this class, derive a class named Circle with another data member named radius. For this derived class, the x and y data members represent a circle’s centre coordinates. The member method of the Point class should consist of a constructor that set the value for x and y to 0, an area() method that return 0, and distance() method that returns the distance between two points.
Additionally, the derived class should has an overided method named area() that return’s a circle area
