attributes can be radius, circumference, area

I do not agree with most of the answers here. MOST ARE WRONG!!!
So let's answer this.
Firstly, Definitions or Analogy.
- Attributes are what you can use to describe an object. e.g "black" hair, "blue" eyes, "long" legs etc.
- Behaviours includes how those attribute works.
So in short, Behaviours can work on Attributes but Attributes Cannot work on Behaviours.
Back to your Questions and the answers provided...
1. Radius: is an attribute because it is a measure of the part of a circle. NOT how a part works!
2. Circumference: is a BEHAVIOUR!!! don't be confused to think this is an attribute (property) because it is the distance round a circle. It is actually a behaviour that depends on the radius and value of PI. remember circumference = 2 × PI × r. If you will be coding this, you will make it a method (behaviour) not a property (attribute) .
3. Area: is a BEHAVIOUR!!! same reason as no 2
4. Diameter: can be either be an attribute or a behaviour depending on how you intend to see it. If you want to see it as a function of radius, then it is a BEHAVIOUR. else attribute.
I believe, by now, you should understand how to classify behaviour (methods) and attributes (properties).
In summary, if what you want to classify can be written as a function, then it is a behaviour of some properties...

attribute will be radius

createCircle() will be behavior

attribute will be the radius,diameter,circumference and area.. behaviour can be semicircle,segment of circle.. like how all circle can change with angle..

thanks
and what about its behaviour......

thanks alot everyone..it helps...

behavior could be like Circles rolls.
