Ha, great question! The wafers are round because they are cut from a solid silicon cylinder called an "ingot". The ingot is cylindrical because it is created through a rotational "pulling" process from sort of a crucible of molten silicon. There is always some loss of silicon wafer area because it isn't possible to completely tile the wafer with the rectangular dies. As the starting wafer is not that expensive, it's overall not a big deal.
