Getters for set properties
In previous videos we used a getter method to retrieve a backing property declared in a setter. In this answer section the area and circumference properties are called through dot notation. Can you explain why?

Getter methods and ordinary properties are both accessed through dot notation. Calling a getter looks exactly like a reference to a property in the code.
But the reason area and circumference don't need getter methods is that they are set by the radius setter method and don't have setters of their own. Since there are no setters using the same name, they can be ordinary properties.
