Actually TRY what that description asks!!

--------------------------
SurfaceArea = 4pi%2Ar%5E2
volume = %284%2F3%29pi%2Ar%5E3
--------------------------

r is the radius. Now you want to use 2r and find what each of those formulas shows.

New Surface Area, 4pi%282r%29%5E2=CanYouFigureThisOut?

New Volume, %284%2F3%29pi%282r%29%5E3
%284%2F3%29pi%282%5E3%29%28r%5E3%29


Think about those changes............


CONCLUSION
--------------------------------------
Doubling the radius changes s to 4s.
Doubling the radius changes v to 8v.
