Answer:

Explanation:

lenght of the arc = pie x r x angle / 180

                           = 22/7 x 9 x 240 / 180 ( angle of reflex = 360 -120

                                                                                            = 240)

                           = 22/7 x 9 x 4/3

                            = 22/7 x 3 x4

                            = 22/7 x12

                            = 264/7

now area of shaded region = area of big sector

                                               = pie x r² x angle / 360

                                               = 22/7 x 9 x9 x 6/9

                                            = 22/7 x 54

                                               = 1178/7
