ok /sci/ heres one I'd like to see you solve. I know for a fact I need to level my calculus more for this one, but right now I'm busy C grinding.

a hollow cone [dunces hat]:
    /\
   /  \     \slant height = 30cm
  /    \
 /      \
(________* <- A fly on the very rim
|____| <- radius = 10cm

Diametrically opposite the fly (opposite rim) is a patch of honey, the fly can only walk along the wall of the cone, what is the shortest possible route it can take to get to the honey?
