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

well, a ratio is the quotient of two numbers. I'd say a constant ratio is where both values are constants. For example, if x/y is a constant ratio, then it means that there is some number k such that x/y = k.
