Actually TRY what that description asks!!

--------------------------
SurfaceArea =
volume =
--------------------------

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

New Surface Area, ?

New Volume,



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


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