Question

The radius of one sphere is twice as great as the radius of a second sphere.

Find the ratio of their volumes.


1/2

1/4

1/8

1/16

Answer 1

volumr = 4/3*pi*r^3

Answer 2

i dont get any of this at all.. :-/

Answer 3

4/3)*pi is constant

Answer 4

so volume depends on r^3
r=radius

Answer 5

r1 = 3x
r 2 = x
a1/ a2 = 4/3)pi (r1^3)/ 4/3)pi r2^3

Answer 6

so its b ? o.O

Answer 7

\[\frac{V1 }{ V2 }=\frac{ r1^3 }{ r2^3 }\]

Answer 8

im sorry, i suck at this very bad..

Answer 9

lol cube 1/2^3=1/8

Answer 10

lol thanks !
