Homework Statement
A water tank is built in the shape of a circular cone with a height of 6 m and a diameter of 10 m at the top. Water is being pumped into the tank at a rate of 2m^{3}
per minute. Find the rate at which the water level is rising when the water is 2 m deep.
Homework Equations
Volume of a cone - \frac{1}{3} \Pi r^{2} h
Surface area of a cone - \Pi r s + \Pi r^{2}
The Attempt at a Solution
\frac{dV}{dt} = 2m^{3}/min
I think I have to find \frac{dh}{dt} but other than that I'm completely lost.
