Answer 2

Answer:

Step-by-step explanation:

Area of shaded region = Area of square ABCD − Area of 4 quadrants − Area of circle with diameter 2 cm

Area of square =4×4=16cm ^2

Area of sector =  

360θ  ×π×r ^2

Area of 4 quadrants =4×  

360 90  ×π×1×1

  =3.14cm^2  

Area of circle=π×r ^2

 =π×1×1

=3.14cm ^2

 

∴ Area of shaded region =16−6.28 =9.72cm^ 2
