Answer:
Step-by-step explanation:
so I can't see the picture or what the "Shaded region " is.. but I can guess that it's the part of the 3x3 rectangle with the circle removed.. right?
if that's the case... then
3*3 = 9
9 - area of circle = shaded region
area of circle = pi * 
pi * 1 cm = 3.1415
9
- 3.1415
= 5.8585
5.86
I don't see this as a choice of answers so maybe that's not what the shaded region is. any way.. hope it helps
