Astronomer 107,
Hello!....In response to your question on PF Math board (Sphere). Answer by mathman is incorrect. Volume of sphere is given as pi/6 (diameter^3).
Volume 27=27/0.523=51.56; cube root =3.72 radius;
Volume 8=8/0.523=15.28; cube root=2.48 radius.
Not quite 3:2 ratio. I'm no math person, but a scientist nonetheless and hold to mathematics as the science of describing exacting relationships. Mathman, et al, should hold to it as well and made accountable for better than smug, erronious and sarcastic answers to forum inquiries....Donde.
PS: I'm redfaced!! Mathman IS correct. Also, the figures for radius should instead read diameter. Sorry about that....
