The area of the square is 36. (One side is 6, 6 squared is 36)
The diameter of the semicircles is 6.
(This is known because all sides of a square are congruent)
Therefore, the radius is 3.
The area of one semicircle is 14.1372. Times 2 is 28.274334
≈ 7.74 units²
The radii of the semicircles will be 3, since the side length of the square is 6 and there are 2 semicircles in it.
Find the area of the 2 circles by using the circle area formula.
A = r²
A = (9)
A = 9 or approx. 28.26
Then, find the area of the square.
6 x 6 = 36
Subtract 36 - 28.26 to find the area of the shaded area
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
now we just subtract and our answer is
