Answer 2

Answer:

The answer is (c) 192.5 cm²

Step-by-step explanation:

area of shaded portion = area of the big sector - area of the smaller sector

                                      =  $\frac{90}{360}$ × $\frac{22}{7}$ × 21 × 21 - $\frac{90}{360}$ × $\frac{22}{7}$ × 14 × 14

                                      = $\frac{33 * 21}{2}$ - 22 × 7 (AFTER SIMPLIFICATION OF DIGITS)

                                      =  $\frac{693}{2}$ - 154

                                      =  $\frac{693-308}{2}$

                                      =  $\frac{385}{2}$

                                      = 192.5 cm²
