• 142 Math Wonders to Inspire Teachers and Students The familiar circumference formulas give us C C = 2 r or r = 2 and C +1 C +1 = 2 R or R = 2 We need to ﬁ nd the difference of the radii, which is C +1 C 1 R − r = − = ≈ 0 159 yards ≈ 5 7 inches 2 2 2 Wow!

• As to the shape decision it is just not true we saved anything since the sidewall angle, the shoulder and heatshield radii, at the very least are NOT those of Apollo's.

• The contours themselves correspond to a solid of revolution, with the contour radii given by the x coordinates of the profile points, the elevations by the y coordinates, and the number of points around a contour by twice the number of glass panes around the Gherkin.

• It can be seen that they have some of the highest electronegativities and therefore hold their electrons close, resulting in their relatively small atomic radii, but they are eager to obtain their octets, and are willing to do so by bonding with other atoms to form molecules.

• The noble gases (helium, neon, argon, krypton, xenon, and radon) possess full octets, which they guard closely (notice their high ionization energies and small atomic radii), and tend not to interact with other atoms.

• Some insight into their “social skills” (or lack thereof) can be gained by surveying certain properties such as their ionization energies, electronegativities, and atomic radii.
