<p>A right circular cylinder vase with an inner base radius of 6 inches is filled with water to a height of 20 inches. After a smaller solid right circular cylinder with base radius of 4 inches is then completely submerged in the water, the height of the water is 24 inches. What is the height, in inches, of the smaller cylinder?</p>

<p>I really don't understand what this question is talking about, and an explanation of the problem and/or answer would be helpful.</p>

<p>Thanks.</p>

<p>Nvm guys; I understand it now.</p>

<p>BTW, is the answer 9 inches?</p>

<p>V=kr2h
Vlarge=36x20
Vsmall=16xH</p>

<p>Vlarge+Vsmall = 36x24 = 36x20+16xH</p>

<p>36x4=16xH
36=4xH
9=H</p>

<p>Final answer is [9 inches].</p>

<p>Not too bad.</p>
