Create a base class named Point consisting of x and y data members representing point
coordinates. From this class, derive a class named Sphere with another data member named radius. For this derived class, the x and y data members represent
a sphere’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 volume() method that return 0, and distance() method that returns the distance between two points, (x1,y1)
and (x2,y2), where
Additionally, the derived class
should has an overided method named volume()
that return’s a Sphere volume
Volume = (4/3) × 3.14
× radius³
Draw UML diagram for the class Point
and class Sphere.
