What is the value of the `radius` field in the `yourCircle` object?

100.0 (correct)

The text does not provide enough information to determine the value of `yourCircle.radius`

34.0

5.0

What is the difference between an instance method and a static method?

Instance methods can be called on any object, while static methods can only be called on the class itself.

Instance methods can access instance variables, while static methods can only access static variables. (correct)

Instance methods are defined using the `static` keyword, while static methods are defined without the `static` keyword.

There is no difference between instance methods and static methods.

What is the purpose of the `myCircle` object?

The `myCircle` object is used to demonstrate the use of instance methods and instance variables.

The `myCircle` object is not mentioned in the text, so its purpose is unclear.

The `myCircle` object is used to demonstrate the creation of a new `Circle` object with a radius of 5.0. (correct)

The `myCircle` object is used to demonstrate the difference between instance methods and static methods.
