I hope you realize that for most modern hard drive this question is
meaningless. That is if you really want to know what you're asking.

Since the hard drive changes the size of the cylinders to pack more
data in the outer cylinders. You could try to ask what is the size of
a given cylinder? But it would not serve much, because modern hard
drives remap bad sectors on other cylinder "transparently", and use
really only LBA, even if the CHS addressing is still supported for
legacy.
