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

**Damon**, Monday, July 28, 2014 at 2:38ameasy way:

r = (4/16) h = (1/4) h

surface area = pi r^2

= pi (1/16) h^2

dV = surface area * dh

dV = pi (1/16) h^2 dh

DV/dt = (1/16) pi h^2 dh/dt

hard way:

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

again r^2 = (1/16) h^2

V = (pi/3)(1/16) h^3

dV/dh = (pi/16) h^2

again dV/dt = (pi/16) h^2 dh/dt
