Calculating the resonant frequency of a gas cylinder

[DIYNerd]

I would like to make a bell out of a used compressed gas cylinder, but I would like to tune it to a specific note or frequency, e.g. A (440Hz). Can someone help with a formula to calculate this so I can cut it precisely?

That sounds like fun. I just did a search for "How to tune a bell." It found numerous web pages and Youtube videos on that subject. I suggest that you try several of those sources first. It may be that calculation is not the best strategy.
