Answer 1

Answer:

6.28 cm²

Step-by-step explanation:

For Bigger Circle

Radius= 15 cm

Area₁ = (Pie)r²

        = 3.14 x 15

        = 47.1 cm²

For Smaller Circle

Radius = 13 cm

Area₂  = (Pie)r²

            = 3.14 x 13

            = 40.82 cm²

Area of shaded portion = Area₁ - Area₂

                                        = 47.1 - 40.82

                                        = 6.28 cm²
