''' problem statement : Write a definition f0r a class circle with the attribute center and radius where center is the point object and
radius is the number, instantiate the circle that represents circle with radius 75 and center at (150,100) .
1) write a function with name point_in_circle that takes a circle and point and returns true if the point lies inside or on the boundary 
of the circle
2) write another function named rect_in_circle that takes circle and rectangle and returns true if the rectangle lies inside or on the boundary
of the circle'''
