Because the shapes of our thermals are, in general, much closer to oblate spheroids, we expect the errors involved to be much less than 15%.
Spheroid bodies that number 1 to 20 per cortical granule comprise the densest component of the cortical granules.
The spheroids are arranged in loose colonies of up to some dozens of individuals.
Their spheroid shape is a geometrical generalization by virtue of which we circumscribe the whole to the continuous line which seems to contain it.
An example of waves on a prolate spheroid surface of small eccentricity illustrates the main ideas.
This plays a role similar to the tipped rotation axis or a precessing spheroid.
Of course, if the thermal's shape were a perfect spheroid, the volume computed in this manner would be exact.
The tip of the spheroid is indicated with a dot.
