Exercise1 : Defining Circle type and Creating a Driver Circle class private members double radius double xPos double yPos public members double diameter() get the diameter of the Circle. It returns a value, diameter. double area() calculate the area of the Circle double circumference() calculate the circumference of the circle double getRadius() returns the radius double getX() returns the xPos value double getY() returns the yPos value void setX(double x) sets xPos, no requirements void setY(double y) sets yPos, no requirements double distanceToOrigin() returns the distance from the center of the circle to the origin HINT: Find out how to calculate the distance between two points and recall the origin is at (0,0) bool intersect(const Circle

Please refer below output for reference

Enter xPos yPos circle 1 :0.0 50.0

Enter radius for circle 1 :100.0

Enter xPos yPos circle 2 :50.0 0.0

Enter radius for circle 2 :100.0

Information for Circle 1:

location:( 0 ,50 )

diameter: 200

area: 31415.9

circumference: 628.318

distance from the origin: 50

Information for Circle 2:

location:( 50 ,0 )

diameter: 200

area: 31415.9

circumference: 628.318

distance from the origin: 50

The circles intersect.
