Answer 10

oh, i forgot the circle... see cosketch

Answer 11

What is the radius of the smaller circle? 3 units
What is the radius of the bigger circle? 9 units

Therefore, the area of the smaller circle is A = π(3)² = 9π
The area of the bigger circle is A = π(9)² = 81π

To find the area of the shaded region, just subtract the area of the smaller circle from the larger circle.
