Answer:
20.43
Step-by-step explanation:
area of a circle is r^2 x 3.14
area of circle = 3.14
divide that by 2 because only half of the circle is cut out of the shaded region.
that would equal 1.57
to find the majority of the shaded region just multiply length x width
11 x 2 = 22
so subtract the half-circle from that
22 - 1.57 = 20.43
