Program:  circle.cpp 1: Create a class Circle 2: Create two instances of the Circle class   1: Based on Program 13-1 in the textbook, create a class name “Circle” with the following declarations (hint: you can use PI=3.14):   //Circle class declaration   class Circle { private: double radius;   public: void setRadius(double); double getRadius() const; double getArea() const; double getPerimeter() const;  };        2: Based on Program 13-2 in the textbook, create two instances of the Circle class, pizza1 and pizza2, which can have different size (radius).  You should put your answers for Q1 and Q2 into one program.

class implementation file -- Rectangle.cpp class Rectangle { #include #include "Rectangle.h" using namespace std; private: double width; double length; public: void setWidth (double); void setLength (double) ; double getWidth() const; double getLength() const; double getArea () const; } ; // set the width of the rectangle void Rectangle::setWidth (double w) { width = w; } // set the length of the rectangle void Rectangle::setLength (double l) { length l; //get the width of the rectangle double Rectangle::getWidth() const { return width; // more member functions here

Consider the following class definition: class circle { public: void print() const; void setRadius(double); void setCenter(double, double); void getCenter(double&, double&); double getRadius(); double area(); circle(); circle(double, double, double); double, double); private: double xCoordinate; double yCoordinate; double radius; } class cylinder: public circle { public: void print() const; void setHeight(double); double getHeight(); double volume(); double area(); cylinder(); cylinder(double, double, private: double height; } Suppose that you have the declaration: cylinder newCylinder;   Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle
