Answer
The problem can be restated as follows:
Find $\dfrac{dV}{dt}$, if $\dfrac{dh}{dt}=1\, cm/min$. Where V and h are the volume and water level respectively.
Work Step by Step
Since the water level rises at a rate of $1\, cm/min$.
We get, $\dfrac{dh}{dt}=1\, cm/min$
Since, the problem asked to find the rate at which the water is pouring in.
The problem asked for $\dfrac{dV}{dt}$.
Thus the problem can be restated as follows:
Find $\dfrac{dV}{dt}$, if $\dfrac{dh}{dt}=1\, cm/min$. Where V and h are the volume and water level respectively.
