Answer 1

Answer:

1) Bigger sector = 168.8pi

1) Smaller sector = 56.3pi

2) Bigger sector = 529.9

3) Smaller sector = 176.6

Step-by-step explanation:

1) Bigger sector =  $\frac{270}{360}$×pi×15×15

                          = 168.75pi

1) Smaller sector = $\frac{360-270}{360}$×pi×15×15

                             = $\frac{90}{360}$×pi×15×15

                             = 56.25pi

2) Bigger sector =  $\frac{270}{360}$×3.14×15×15

                           = 529.875

2) Smaller sector = $\frac{360-270}{360}$×3.14×15×15

                             = $\frac{90}{360}$×3.14×15×15

                             = 176.625
