Let's do some cool math: A tank in the form of a right-circular cylinder standing on end is leaking water through a circular hole in its bottom. Suppose the tank is $$10$$ feet in height and has radius $$2$$ feet and the circular hole has radius $$1/2$$ inch. If the tank is initially full, how long will it take to empty? Whoever gets this right first gets a cookie.
