Corner area (4corner) can be found by using area of square 10x10 - circle = 21.5

To find 2 corner.
= 21.5 / 2
= 10.75

The two semicircle can be joint together to form a circle sit inside the square 10x10. Therefore, the radius = 5cm (this is most important parts, else cannot find the corner area).
