9.3 The Chain Rule

Question 8

The depth of water in an experimental filtration vessel, $D\,$ centimetres, varies according to the radius of the sediment layer $r\,$ millimetres, such that $D = (2r^3 + 9r^2)^4$ . Determine the rate of change of the depth with respect to the radius, $dDdr\displaystyle \frac{dD}{dr}$ .
