Let's look at the formula for the volume of a sphere:

                 Volume = (4/3) (pi) (radius)³ .

If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by  (anything)³ .

Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by  ∛(something).

In this question, the ratio of the volumes is  3 .
So the ratio of the radii (radiuses) is  ∛3 = about  1.442  (rounded)
