A hemisphere bowl of radius 12cm is initially full of water. Water runs out of a small hole at the bottom of the bowl at a rate of 48pi cm^3 s^-1. When the depth of the water is x cm , show that the depth is decreasing at a rate of 48/[x(24-x)] cm s^-1(adsbygoogle = window.adsbygoogle || []).push({});

Also, find the rate at which the depth is decreasing when

a) The bowl is full.

b)The depth is 6cm.

Another question is in this picture

Thanks in advance! Really urgent :)
