A fly lands on the outside of a cylindrical
drinking glass 6 cm from the top. Dia-
metrically opposite the fly and 7 cm from
the bottom, but on the inside of the glass,
there is a drop of honey. The glass has
circumference 24 cm, height 10 cm. Find
the shortest path, in cm, that the fly must
walk on the surface of the glass to reach
the honey.
