A bowl with circular cross section and height 20 cm is shown in Figure 2.
The bowl is initially empty and water starts flowing into the bowl.
When the depth of water is h cm, the volume of water in the bowl, V cm3, is modelled by
the equation
V =(1/3)h^2 (h + 4) 0 =< h =< 20
Given that the water flows into the bowl at a constant rate of 160 cm3 s−1, find, according
to the model,
(a) the time taken to fill the bowl (2 marks)
(b) the rate of change of the depth of the water, in cm s−1, when h = 5
(5 marks)

Please don't post solutions - it's against the rules of the forum!

The OP hasn't responded to the question they were asked, so either they've managed to solve it or are still working on it
