The volume V of a right circular cylinder of radius r and height h is V=πr2h. (a) How is dVdt related to drdt if h is constant and r varies with time? (Enter drdt as dr/dt.)

Step-by-step explanation:

Given that the  volume V of a right circular cylinder of radius r and height h is

To find rate of change of V with respect to rate of change of radius

Here given that h is constant

So differentiation with respect to t gives

This would be dv/dt i.e. rate of change of volume with respect to time in terms of dr/dt

This varies whenever r varies

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
