Question

Circle Class

Write a Circle class that has the following member variables:

* radius: a double

* pi: a double initialized with the value 3.14159 The class should have the following member functions:

* Default Constructor. A default constructor that sets radius to 0.0.

* Constructor. Accepts the radius of the circle as an argument.

* setRadius. A mutator function for the radius variable.

* getRadius. An accessor function for the radius variable.

* getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius

* getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2

* getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius

Write a program that demonstrates the Circle class by asking the user for the circle s radius, creating a Circle object, and then reporting the circle s area, diameter, and circumference.
