1. State either these statement are valid or invalid:

Circle c1 = 4, new Point();

Circle c2 = new Circle(4,3,2);

Circle c3 = new Circle(new Point(4,2), 5.2);

Circle c4 = new Circle((4.5+3.2)*10, new Point(5,7));

1. b.What will be the radius of c5 if:

Circle c5 = new Circle(new Point(4,2).getY(), new Point(5,7));
