        Point p = new Point();
        p.x = 15;
        p.y = 15;
        
        Circle circle = new Circle();
        circle.radius = 10;
        circle.center = p;
        Console.WriteLine($"Area of the circle with center at ({circle.center.x}, {circle.center.y}) and radius of {circle.radius} is {circle.area()}");
    }
}

O método retorna um valor double.
Certifique-se de que o método utiliza a palavra-chave public.
