Circle m has the central angle ∠amb with a measure of 63°. which of the following statements does not represent the circle m?

AB is a major arch would be my best guess.
I hope this helps :)

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
