The Watchdog (Posted on 2004-10-28) Difficulty: 5 of 5
A watchdog is tied to the outside wall of a round building 20 feet in diameter. If the dog's chain is long enough to wind half way around the building, how large an area can the watchdog patrol?

Rock on! Yeah, I double counted the building :-(.

(250Pi^3)/3 is now a beautiful thing.
