Default Some Questions

All right. So I need to find the volume of a cylinder.

2 things.

1. How do I find the height of a cylinder?
2. The formula to find this problem is: pi x r(squared) x height. So if the question asks you to find the volume in MM, would the answer end up being: answer(cubed)?

Default Re: Some Questions

1. h=height
SA=surface area

If you're given the volume and the radius of that cylinder, then
h = v/(pi*r)
If you're given the surface area and the radius of that cylinder, then
h = SA/(2*pi*r) - r
If you're only given volume, surface area, or radius (only 1 of them), then it's impossible to determine height, but I may be wrong.

2. Yes, it would look something like "33mm"

Don't hold it against me if those are wrong, but they seemed to work out with the numbers I put in.
ASUS A8N32 SLI-Deluxe, AMD Athlon X2 3800+ @ 2.8GHz, eVGA 8800GTS 320MB, 2GB Corsair XMS DDR400, 160GB WD HDD + 320GB Seagate Barracuda 7200.10, AC Freezer 64 Pro, 700W OCZ GameXStream, NZXT Zero :D

I think I've decided to leave... maybe I'll come back sometime.
