Creating "floors" from a revolved surface

Hi guys I think this is a simple one.

I have a curve which I have revolved around a centre point. That revolved surface is divided in the vertical direction giving me floor heights. I don't know how to get these division lines to give me the floor slab. Is anyone able to give me a hand at what I should do?

Thanks
