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 • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

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