Answer:


A_s=179 \ yd

Explanation:

Area of Circle can be calculated using following formula


A=\pi r^(2)

Where r is radius of circle

Area of outer circle (r=11 yd)


A_1=\pi (11)^(2)\\A_1=379.94 \ yd

Area of inner circle (r=8 yd)


A_2=\pi (8)^(2)\\A_2=200.96 \ yd

Area of shaded region


A_s=A_1-A_2


A_s=379.94-200.96\\A_s=179 \ yd
