Thank you! So many videos online for rate of change with Volume in regards to radius, or Area in regards to radius. Finally a video that combines both. You definitely saved me 10 marks on my upcoming final!!

Thanks for this video. However, I have a question about the unit because when I traced it supposedly the dr/dt have a meter unit then the r has a m unit as well, do we consider it as m squared if we multiply it?
