**bobpursley**, Wednesday, November 14, 2007 at 8:07pmWrite the volume equation as a function of radius..

v= PI*r*heightcyclinder + 4/3 PI r^3

Put numbers in...I dont see height in the problem given.

dV/dT= 261

When r=3, V= 144, and dr/dt= 2

Find dh/dt

dv/dt= PI*dr/dt*height + dh/dt*PI*r + 4PIr^2 dr/dt

you can find dh/dt here, once you solve for height in the volume equation
