Discussion of Problem 1215. Exactness of Projectile Hit

The Punisher Why the answer on sample is 2.000? [1] // Problem 1215. Exactness of Projectile Hit 21 Aug 2006 14:32

Why the answer on sample test is 2.000? I think it should be 1.000. Could anybody explain me? Thanks.

The problem asks for the "minimal diameter of a projectile" not the radius.
