In the square below, the two semi-circles are congruent. Find the area of the shaded region. If necessary, round your answer to
Jobisdone [24]
Let's start with the area of the square
area \: square = s \times s = 8 \times 8 = 64
now let's subtract the are of the two half circles.
two half circles are the same as one circle, and we know that the diameter of the circle is 8 (same as the side of a square) so it's radius is 8/2= 4 inches

area \: circle = \pi {r}^{2}  = \pi \times  {4}^{2}  = 16\pi
now we just subtract and our answer is

64 - 16\pi = 64 - 16 \times (3.14) = 13.73
