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.
---------------------------------------
