CS110 Circle

Requirement

In this Assignment, you should write a class that, given a circle’s radius, has methods that return the circle’s area, diameter, and circumference.

In case you have forgotten, the equations for a circle’s area, diameter, and circumference is given below.

1   area = πrr

2   diameter = 2r

3   circumference = 2πr

Based on Chapter 3, Programming Challenge # 8 Circle class in your textbook. Your output is given below.

1   Enter the radius of a circle: 5.3

2   The circle's area is   88.2472631

3   The circle's diameter is   10.6

4   The circle's circumference is   33.300854

Write a separate class called CircleDemo with a main method that asks the user for the circle’s radius, creates a Circle object, and then reports the circle’s area, diameter, and circumference using the circle’s getter methods.
