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?

(In reply to Semi-lar thoughts by Leming)

I had the same approach.  

Cutting the shape removed from the circular disk in half might be still considered to have crossed the center point.  By cutting the shape into three or more pieces, crossing the "virtual" center of the circular disk can be avoided -- as you did in your example.
