I post in the voice of Christopher Walken
American English is pretty varied. I am actually trying to think of how people where I live pronounce Centaur and I am pretty sure it isn't 'centar' here. But I'd need to grab someone with a thicker accent and ask them to say it (and now I am too conscious of the question to say it honestly myself lol)
EDIT: Also I am pretty sure I say pronounce the 'aur' like in dinosaur
