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 $cm^{2}$

9 - area of circle = shaded region

area of circle = pi * $r^{2}$

pi * 1 cm = 3.1415  $cm^{2}$

9 $cm^{2}$  - 3.1415  $cm^{2}$ = 5.8585 $cm^{2}$

5.86 $cm^{2}$

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
