Simulation distance description in the new UI is nonsensical and misleading

The text under the simulation distance selector in the new UI describes each simulation distance in terms of an "N x N block radius" (e.g. "64 x 64 block radius" for simulation distance 4). This wording is nonsense: a radius a one-dimensional measurement; "N x N" describes an area, not a radius.

Moreover, an N x N area is much smaller than an N-radius area:
64 x 64 = 4906
3.14159 * 64 ^ 2 = 12,868

Finally, assuming the intended meaning is "a N block radius", the full text is not strictly correct. "Loads and applies changes within a N block radius" is not how the game works and does not make explicit the connection to the simulation distance being chosen.

A more accurate description would be "loads and applies changes in chunks that come within a (simulation_distance x 16) block radius." However, if the mention of "chunks" and multiplying by the number of blocks in a chunk seems too technical, it could be phrased obliquely as "loads and applies changes based on a N block radius."
