**Steve**, Thursday, February 28, 2013 at 4:24pmat water depth y, the radius of the surface is 2y/5, so y = 5r/2

v = 1/3 pi r^2 h = 1/3 pi (25y^2/4)(y) = 25pi/12 y^3

dv/dt = 25pi/12 * 3y^2 dy/dt = 25pi/4 y^2 dy/dt

3 = 25pi/4 * 25 dy/dt

dy/dt = 12 / 625pi

Seems kinda slow - better double check my algebra

r = 2y/5

Make that change and follow it through
