    I assume that you know the formulae for volume and surface area of a sphere. The only variable that each quantity depends on is r, so when you do \frac{dV}{dt} you can find \frac{dr}{dt} - which will depend on r and the constant given in the question - and use that to calculate \frac{dA}{dt}.

    Ok we have \frac{dV}{dt} and we want \frac{dA}{dt}.

    You should know what the volume and surface area of a sphere is. Can you work it out now?
