Answer:
3.8 
Step-by-step explanation:
We are given a square of size 6x6 in. So, area of this square is equal to 6 x 6 = 36  . Now, the shaded region is
. Now, the shaded region is  x (Area of square - area of semicircles)
 x (Area of square - area of semicircles)
The diameter of both semicircles = side of the square = 6in 
So, radius (r) =  x diameter =
 x diameter =  x 6 = 3in
 x 6 = 3in
And hence, area of semicircle is  =  x π
 x π
 =  x π
 x π 
 
Since, there are two semicircles we multiply above by 2, so area of both semicircles = 2 x  π
 π = 9π
 = 9π
Area of shaded region =   (36 - 9π) = 3.8628 = 3.8
 (36 - 9π) = 3.8628 = 3.8  to the nearest tenth.
 to the nearest tenth.
