2    private double radius;

3

4    public Circle (double radius) {

5    radius = radius;

6    }

7

8    public double getRadius() {

9    return radius;

16

17    class B extends Circle {

18    private double length;

19

20    B(double radius, double length) {

21    Circle(radius);

27    length = length;

23    }

24

25    @Override

26    public double getArea() {
