a semi circle? Hmm. A scroll saw may work well, but I doubt you have one of those. I would try cutting it a little large, and as smooth as you can, and then find a way to clean it up afterwards by sanding the edge. If you need it to be really precise, the only way is to pivot around the center against some kind of sanding or cutting apparatus.
How thick is your plastic?
