Answer 1

Hey there!

Answer:

76.92 cm² (approx.)    

Step-by-step explanation:

Area of sector 1 = πr²∅ / 360

                          = (3.14 * 7 * 7) * 80 / 360

                          = 12308.8 / 360

                          = 34.19 cm²

Area of sector 2 = πr²∅ / 360

                           = (3.14 * 7 * 7) * 60 / 360

                           = 9231.6 / 360

                           = 25.64 cm²

Area of sector 3 = πr²∅ / 360

                           = (3.14 * 7 * 7) * 40/360

                           = 6154.4 / 360

                           = 17.09 cm²

Now,

area of shaded region = ar. sector 1 + ar. sector 2 + ar. sector 3

                                      = 34.19 + 25.64 + 17.09

                                      = 76.92 cm² (approx.)
