You cannot because the volumes of the cones also depend on their heights.

Not enough information has been given but the volume of a cone is 1/3*pi*radius squared *height and its base area is pi*radius squared

Reduce it if possible. Then set it equal to the similarity ratio of a-cubed over b-cubed, take the cubed route and theres your answer.

The ratio of the volumes of similar solids is (the ratio of their linear dimensions)3 .

Notice the exponents in these two statements.Those little tiny numbers tell the whole big story:(the ratio of the surface areas of similar figures) = (the ratio of their linear dimensions)2(the ratio of the volumes of similar solids) = (the ratio of their linear dimensions)3
