<p>isn't there something special with a cone if you cut it in half with the cut being parallel to the base? like some kind of special ration between the top and the bottom or the top and the whole cone?</p>
<p>also...what are the volume and area ratios of solids?</p>
<p>For the real math sat problem liek that, you need to know that two similar triangles are in proportion thus you can use ratios to get 24. I think that's what your asking?</p>
<p>i'm not sure if it's the real math problem, but it's something like this:
a cone with base radius 6 is cut 8 units up. the radius of the new cone is 4. what is the height of the entire cone.</p>
<p>Yeah. Similar triangles.</p>
<p>So 4/6 is ratio between 2. Thus, 8 is 1/3 of the total height. So 8 x 3 = 24 = the height.</p>
<p>use the similar triangle property.
(height of the smaller cone)/4 = (height of the entire cone + 8)/6
solve that give 16 as the height of the smaller cone. add 8 gives 24.</p>
<p>the v: area for solids differs for each solid. Just put the forumla for volume on one side and the formula for solid on the other. Solve the equation to get the ratio.</p>
<p>oops...wow that was easy
i could have sworn there was some different kind of ratio or something...</p>
<p>thanks guys</p>
