Homework Help: geometry-finding ratio

Posted by jen on Tuesday, May 22, 2007 at 4:11pm.

Ratio of the heights of two similar cones is 7/9

what is the ratio of their radii? ratio of their volumes??

TIA

If they are similar, the ratio of the radaii is the same.

Now consider that the volume of a cone is 1/3 PI r^2 * h

So the volume ratio will have a (7/9)^2 * 7/9 ratio
