## Homework Statement

Water is leaking out an inverted conical tank at the rate of 50L/min. The tank has a diameter of 10m at the top and is 6m deep. if the water is rising at the rate of 4cm/min when the greatest depth is 3m, find the rate at which the water is being poured into the tank.

## Homework Equations

V =1/3 pi r^2 h

## The Attempt at a Solution

dv/dt= -50L/min

dd/dt = 4cm/min

then when it says find the rate at which the water is being poured into the tank. Im not sure what to do with this since we already have a dv/dt
