A square with a side length of 10 cm is used to draw a semicircle with four sides as the diameter. What is the area of intersection of these four arcs?
You can divide the square into four parts along the diagonal, subtract one fourth of the square area (an isosceles right triangle in a semicircle) from the area of the semicircle (diameter is 10), and multiply the result by 4
