Water is flowing into a conical vessel 24cm deep and 12cm across the top at the rate of 100cm^3/min.how fast is the surface rising when the water is 10cm deep?
----------
Find the volume of the cone in terms of the height.

Vol+=+pi%2Ar%5E2%2Ah%2F3
h = 24, r = 6 --> r = h/4
Vol+=+pi%2A%28h%2F4%29%5E2%2Ah%2F3
Vol+=+pi%2Ah%5E3%2F48
dV/dt =pi%2Ah%5E2%2F16dh/dt}
dh/dt = 100/(pi*100/16)
dh/dt = 16/pi cm/minute
