If I have a square with four quarters of a circle, how can I find the area not filled in by the circles? What I'm asking is here:
My drawing is har from perfect, but I think you get what I mean. I'm trying to find the area of the space where the arrow is pointing. Here are my thoughts on the problem:
The square is 24 inches by 24 inches, meaning its area is 576. Four quarters of a circle make a circle, and the radius of the circle is 12. To find the area of the circle, I do pi*12^2, which is 144pi. So does that mean the area of the space in between the semicircles is 576 - 144pi, or can the answer be further simplified without doing 144 * pi?
