Create a class to model a circle. Name this class Circle 

1. The class should include data members for radius, x and y. 

2. Include a default and explicit constructor. The explicit constructor will receive a radius value and an x.y coordinate. Make sure that the default constructor sets the radius to 1 x.y position to 1,1 

3. Include setter/getter member methods for each data member. 

4. Include methods for computing the circumference and area 

Test this class by instantiating Circle objects as follows: 

• Instantiate three Circle objects, cl,c2, and c3. Use explicit values in the construction of cl and c2. Allow the default constructor to assign default values to c3. 
• Use the setRadius0 setter method to re-assign cl a small radius value and c2 a larger radius value. 
• Do NOT re-assign the third circle a radius value; instead, retain the value assigned at construction. 
• Display all the values for all the Circle objects
