How big would a ring-shaped space station need to be, and how fast would it need to spin, to generate 1G gravity, with 3 full rotations in a 24-hour period?

Additional context: I'm designing a sci-fi setting, and I want the primary location to be a very large space station. I am not at all a maths person, and this is a cyberpunk setting so I'm not leaning too heavily on hard science, but I want to have an idea of scale and speed.

Also! I'm not married to the 3-rotations idea, that's just something I'm going with for now but I can easily run with something else.

To be clear; I've googled this and all I'm able to find is calculations that are beyond my very simple comprehension of math. Especially since most of the ones I'm finding tend to assume I'd know how large the station is to begin with, which I don't.
