@sibrosan@mastodon.social @divbyzero@mathstodon.xyz In more formal "Weierstraß style": For *whatever* relative difference ε > 0 we might be willing to neglect, there is a thickness δ > 0 such that |vol_planar - vol_conic| / vol_conic < ε for all shells with thickness δ or thinner, that is, for any r with R-δ <= r < R.
