8. 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.
