Water is flowing at a rate of 5 meters cubed per second into the conical tank shown at the right. (the conical tank is an upsidedown cone that has a diamater of 60 meters and a height of 120 m. and then there's water filled into it and the height is "h", and it doesn't tell you the radius. )
a. Find the volume "V" of the water as a function of the water level "h".
the answer in the back of the book says: [(pi)(h cubed)] over 48.
but i got [(pi)(h cubed)] over 12.

please help.
thank youu!! :)
