Answer:

9:4

Step-by-step explanation:

Volume Big Sphere : Volume small Sphere

4/3 x pi x R^3             :      4/3 x pi x r^3  

R^3                             :      r^3  

27                               :       8

∴ R= 3\sqrt[]{27} \\                   r = \sqrt[3]{8}

      = 3                          = 2

SUrface Area big : Surface area small

4 x pi x R^2          : 4 x pi x r^2

9                            : 4
