66/7 is the answer that is

Answer 2

Answer:

3π sq units

Step-by-step explanation:

Area of Shaded Portion = Area of Complete Circle - Area of Unshaded Circle

Area of Complete circle = $\pi R^2=\pi (2)^2=4\pi$ sq units

Area of Unshaded Circle = $\pi r^2 = \pi (1)^2=\pi$ sq units

Therefore Area of Shaded Part = $4\pi -\pi =3\pi$ sq units
