Question 1198681
the volume of a sphere is tripled. what is the increase in surface area if the the radius of the original sphere is 50 cm?
--------------------
SA of the original sphere is 4pi*r^2 = 10000pi sq cms.
----
3x the volume ---> {{{root(3,3)}}} times the radius.
---
The larger SA is {{{root(3,9)}}} times the original SA.
The increase in SA is {{{(root(3,9) - 1)*10000pi}}} sq cms.
Increase = ~ 10800.838*pi sq cms
