Answer 1

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
