Shorten the pole to less than my height

Well, these are pretty good answers for the various estimates. I get 274.19467

A goat is tethered to a round silo of radius 10 by a rope of length 100. How much grass can the goat graze?

121.14 seems to be correct. The area eaten by the goat is (29pi)^3/(3*29) +(29pi)^2+pi/2 = 21730.2. The field is x^2*pi=2(21730)+29^2*pi (no grass in the silo area so the radius is a little bigger)
