Answer 1

Answer:

103.73cm²

Step-by-step explanation:

=> Area of shaded region = (Area of circle) - (Area of unshaded region)

=> Area of shaded region = (πr²) - (πr²)

                                           = ($\frac{22}{7}$ x 7 x 7) - ($\frac{22}{7}$ x 4 x 4)

                                           = (154 - 50.27)cm²

                                           = 103.73cm²
