In order to illustrate the estimation of an orthocone radius from a fractured segment, consider the following scenario. Given a crushed shell segment with a linear length of 47 mm and a height 16 mm, the third side of the right triangle (= b/2 of Fig. 5B) is 44.193 mm (via Pythagorus' Theorem). Once these three values have been obtained, the radius of the circle that includes the fractured shell segment can be estimated from the series of equations in Figure 5B as:
