Question

Write a Circle class that has the following member variables;

· radius: a double

· pi: a double with value 3.142

· 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 = 2 * radius

· 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 the Circle object, and then reporting the circle area, diameter, and circumference.
