Question 873135
Actually TRY what that description asks!!


--------------------------
SurfaceArea = {{{4pi*r^2}}}
volume = {{{(4/3)pi*r^3}}}
--------------------------


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


New Surface Area, {{{4pi(2r)^2=CanYouFigureThisOut}}}?


New Volume, {{{(4/3)pi(2r)^3}}}
{{{(4/3)pi(2^3)(r^3)}}}



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



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