    dh/dt = 0.318 in/min

    Explanation:

    Given that

    dV/dt = 16 in³/min

    Volume of the cylindrical pot

    V = πr²h

    r=radius

    h=height

    Given that

    d=h = 8 in

    h = 2 r

    radius of cylinder r = 4 in

    V = πr²h

    V = 16πh

    By differentiating with respect to time t

    dV/dt = 16π dh/dt

    Given that

    dV/dt = 16 in³/min

    16 in³/min = 16π dh/dt

    dh/dt = 0.318 in/min
