e e by the S. 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 cir- cle's radius, creating a Circle object, then reporting the circle's area, diameter, and circumference. e . * Make sure to make appropriate methods const methods * Create 2 Circle objects (one using default constuctor, one by passing in a non 0, positive arugment, using non-pointer circle variables. Call the getArea, getDiameter and getCircumference methods and diplay the results. * Write a destructor that simply has a cout statement noting the circle is being destroyed Create a pointer to a Circle, create a new Circle object with a non zero positive radius and set the pointer to point to it. * Call the circle get Area, Diameter and Circumference methods using the pointer to a circle and display the results. * delete the memory for this newly created circle (you should see the destructor message when running) * You should have 3 files in your project that you have created, Circle.h, Circle.cpp and a test .cpp file with your main() in it
