Step-by-step explanation:

Arc length of the circle is given by,

Arc length =

Area of the sector of a circle =

22). Arc length of the circle having central angle =

                                                                                 = 60°

Arc length =

                 =

                 = 7.33 cm

23). Arc length of the circle having central angle = 225°

Arc length =

                 = 12.5π

                 = 39.27 km

24). Central angle =

                              =

                              = 225°

Area of the sector =

                               = 43.20 yd²

25). Area of the sector =

                                      = 65.97 yd²

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
