1. The problem statement, all variables and given/known data Find the surface area of a sphere whose volume is .2 m^3. For full credit, do it without finding the radius. 2. Relevant equations This can be solved using v= 4/3(pi)r^3 and sa= 4(pi)r^2, but my prof doesn't want that. 3. The attempt at a solution so if you manipulate the volume and surface area formulas you can get that the sa:v ratio is 3/r, by cancelling the variables and such. I don't know where to go from there, though, even after reading about the surface area to volume ratio. I did solve the problem using regular math (I got 1.7 m^2) but I haven't been able to do anything else useful without solving for r. Thanks in advance for any help.
