Answer 2

Step-by-step explanation:

Consider big circle

Diameter = 42 cm

Radius = 21 cm

so area = π r²

= 3.14 × 21 × 21

= 1384.74 cm²

Now consider small circle

Diameter = Radius of big Circle = 21 cm

so radius of small circle = 10.5 cm

Area = π r²

= 3.14 × 10.5 × 10.5

= 346.18 cm²

Area of shaded region = Area of big circle - Area of small circle

= 1384.74 - 3.46.18

= 1038.56 cm²
