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

1/3 + 1/5 = 8/15.
