i do believe the answer is 41pi cm2

Answer 2

Answer: 40 pi cm^2

Step-by-step explanation: the area of a circle is pi*r^2. the shaded region is the area of the large circle minus the area of the small circle. the larger circle has an area of 49pi and the smaller circle has an area of 9pi. 49pi-9pi is 40pi cm^2
