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?
Actually, it should be about 6 times the area of the building. Less the building, makes it 5 times the area the building or 1570.796327 square feet.
