Based on your question, I could only find it's cross-sectional area(2πr) and mass. Somehow there is not enough data such as density of the substance which is needed to find the volume of the circular plate. If you know it, then you can find it.
Density = mass/volume = mass/ (area x thickness)
Let's say density is 10.5g/cm³(silver)
10.5 = (53.6 x 1000) / (2πr x y)
53600/10.5 = 0.805 x y
y = 6341.3 m
Too thick right? Maybe the substance is aerogel. The world's lowest density solid so that it might be mm thick.

Hey,
I think we're missing part of the question. We'd need the density or some property about the plate like the volume to calculate that.
Thanks,
Matt

You would need to know the density of the plate's material to answer this question. Read over the question again and think carefully about what you are asking. Obviously, if the plate was made of ceramic it would need to be thicker than one made of lead.
