<p>Heys guys...can you show me how to do 2 problems below? I don't know why but the wording is just confusing me...</p>
<p>and I don't mean to sound obnoxious but can multiple people try to solve these 2 problems because my answers need to be 100% correct and I just wanted to confirm with several people. Thanks! :) </p>

<li><p>Water is draining out of a conical tank at a constant rate of 4 feet cubed per minute. Before the tank began draining, the depth of water was 12 ft and the diameter of the waters surface was 8 ft. How fast will the water level be falling when half the water has drained from the tank?</p></li>
<li><p>A submarine passes directly beneath an enemy destroyer. The sub is 200 ft below the surface of the water, moving northeastward at 40 mi per hour. The destroyer is sailing due south at 25 mi per hr. At what rate will the vessels be seperating after 1/2 hour?</p></li>
