The spelling centre is standard in UK English. In Canada it is typical in proper names, e.g. Toronto Centre for the Arts'', but "center" is also commonly used otherwise, e.g. ''shopping center'', ''center of town . Both spellings can be encountered even in the same text, e.g. in NHL hockey where there are many Canadian and US teams, reference might be made to the "center" forward position and a "centre" where a game is played.
The indirect object of the intransitive verb is given the prepositions (on), (in), (at) or (around). (term) is primary used only in mathematical contexts.
Merriam-Webster's Collegiate Dictionary observes that (term) is objected to by some people on the grounds that it is illogical, but states that it is an idiom, and thus that such objections are irrelevant. It offers (term) as an alternative to (term) for those who would avoid the idiom.
