With regular spherical and hyperbolic geometry, yes, it is flat-ish if you look at a small enough area. On the other hand, if you have a different distance metric, the ratio of a circle's diameter to circumference can be a different constant. For example, in taxicab geometry, it is 4

- HPsquared 5y agoIn London geometry, the distance depends where you are in the one-way system.
- milesvp 5y agoI know this is sort of a low quality joke post, but I don’t think I’d ever thought about a directed taxi-cab distance before. I’m not yet convinced it’s a useful model outside GIS, but I may spend considerable time today thinking about it. Thank you.

- KineticLensman 5y agoTIL that Taxicab circles are squares with sides oriented at a 45° angle to the coordinate axes.
- HPsquared 5y agoIt depends if you define a circle as "constant distance from centre point" or "minimum (circumference/area)".
