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?

See, I had told you earlier how much I liked your solutions.

The mistake I made with my approach is that I used two 20 foot coins and one of them should have been a 31.4 foot coin. Gosh, how blonde can one girl be? So, like, tomorrow I'm going to buy some Clairol Hydrience or maybe Nice 'n Easy and see if that will help.

Congratulations, Nikki. Hugs. CeeAnne
