Recall that the volume of a right circular cone with height h and radius of the base r is given by

V=(pi*(r^2)h)/3

- Math -
**bobpursley**, Thursday, October 15, 2009 at 4:57pmIf you are in calculus...

V=PI *r^2 * r/3 because r and h are the same

or

V=PI *h^3 /3

dV/dt=PI*h^2 dh/dt

You know dv/dt as 20ft^3/min

solve for dh/dt.
