Question 1139791
<br>
Your question doesn't make any sense; so I don't know what you were asking....<br>
The ratio of volumes is 8:27 = (2^3):(3^3).<br>
Since all spheres are similar, that means<br>
(1) the ratio of any measurements of length on the two spheres is 2:3; and
(2) the ratio of area measurements on the two spheres is (2^2:(3^2).<br>
This is an example of a very powerful general concept regarding similar figures.<br>
In any two similar figures, if the ratio of linear measurements (scale factor) is a:b, then the ratio of area measurements is (a^2):(b^2), and the ratio of volume measurements is (a^3):(b^3).
