Question 715784: Hi, my name is Allen and I've been struggling with geometry since I learned it 7 years ago. I need help solving this problem. Thanks!
A tin can with a circular base has a volume of 27(pi)cm^3 and the surface area of the vertical (curved) side is 18(pi)cm^2. What are the dimensions of the can?
Radius = cm
Height = cm

You can put this solution on YOUR website!
Area:
%0D%0A2pi%2Ar%2Ah=18%0D%0A
which we write as
%0D%0Ah=18%2F%282pi%2Ar%29%0D%0A


Volume
%0D%0Api%2Ar%5E2h=27%0D%0A
After substituting and solving we get r=3
which means h=3%2Fpi
