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 [tex]cm^{2}[/tex]

9 - area of circle = shaded region

area of circle = pi * [tex]r^{2}[/tex]

pi * 1 cm = 3.1415  [tex]cm^{2}[/tex]

9 [tex]cm^{2}[/tex]  - 3.1415  [tex]cm^{2}[/tex] = 5.8585 [tex]cm^{2}[/tex]

5.86 [tex]cm^{2}[/tex]

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
