3. A tank shaped like a right circular cone, vertex down, is 9 feet high and has
a diameter of 8 feet. It is initially full of water. (a) Determine the time
required to drain the tank through a circular hole with a diameter of 2 inches
at the vertex. Take k =0.6. (b) Determine the time it takes to drain the
tank if it is inverted and the drain hole is of the same size and shape as in
(a), but now located in the new (flat) base.
