1. The problem statement, all variables and given/known data The volume V of water in a particular container is related to the depth h of the water by the equation dV/dh below. If V = 0 when h = 0, find V when h = 4. 2. Relevant equations dV/dh = 16 sqrt(4-(h-2)2) V(0) = 0 V(4) = ? 3. The attempt at a solution I have not gotten the ODE in a form that I can integrate using separation of variables. I have gotten to the point dV/dh = 16 sqrt(-h2+4h) but this doesn't help much.
