Implement in C#, define an interface CircleA that has a property and one method Compute. The method will compute the area of a circle. It has an integer parameter representing the radius of a circle, and returns the area of a circle represented as a double value. The property will set/retrieve the value of the radius. -define an interface CircleB that has one method Compute that will compute the perimeter of a circle. The method has an integer parameter representing the radius of a circle, and return as the perimeter of a circle represented a double value. -define a derived class that will implement the member(s) of each interface. hint: implement separately -define a test class that will create an instance of the derived class. The instance will call each class object implementation method and then call each interface method. In addition, the instance will set/retrieve the radius via the property defined in the interface CircleA.
