Two Semicircles (Posted on 2007-04-27) Difficulty: 3 of 5
A circular disk can be cut into two semicircular pieces easily by cutting along a diameter.

Can the disk be cut into pieces which can be arranged into two semicircles, with none of the cuts passing through the center?

Remove a square whose center is the center of the circle.

Cut the disk in half.

Cut the top 1/4th and the bottom 1/4th of the square. Re-apply the top and bottom to one semicircle, and the middle to the other.
