Similarly, you can reattempt this question using chain rule, dA/dt * dr/dA = dr/dt.
Anyways intuition for this type of question is always start with the area of the shape/ volume..., that you start to do the derivative. You think about chain rule or derivative with time.
Pls check whether my calculation is correct, there might be careless mistake
