Answer:
4 - pi
Step-by-step explanation:
we see that the inner square leg is 2 inch because its radius + radius
which is 1+1 (two circles diameters are 4 inches, so one circle has 1 inch radius) square area = 4 inches.
we subtract the area of 4 circle quadrants which is a circle area.
area of the circle is pi r^2, r = 1 so A = pi inch
the shaded region is (4 - pi) inch squared.
