?>Shape` and `Color`, and a class `Circle` that implements both of these interfaces. The `Circle` class has two private attributes `$radius` and `$color`, and two methods `getArea()` and `getColor()` that implement the methods defined in the `Shape` and `Color` interfaces, respectively. Circle` class and call its `getArea()` and `getColor()` methods to get the area and color of the circle, respectively. The output of the program will be :Area of circle is: 78.539816339745
Color of circle is: red
