Given: This class is poorly encapsulated. You need to change the circle class to compute and return the area instead. What three modifications are necessary to ensure that the class is being properly

The correct answer is A. Change the access modifier of the setradius () method to private B. Change the getArea () method C. When the radius is set in the Circle constructor and the setRadius () method, recomputed the area. A: There is no need to have SetRadius as public as the radius can be set through the Circle method. B: We need to return the area in the GetArea method. C: When the radius changes the Area must change as well. Incorrect answer: D: the GetRadius() method does not change the radius
