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

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