The solution is:
A rectangle with vertices (0,0), (4,0), (4,6) and (0,6) is revolved about the x-axis to create a cylinder. What is the volume of this cylinder?
E.NOTA (none of these above)
I'm thingking of NOTA. But it confuses me at the part where it says "revolved about the x-axis", i don't know if the way I understand it is correct, because if it's not then I definitely solved it wrong :P
