The number would be 2666. 6 is repeated 3 times. Rounded to the nearest hundred is 2700 and rounded to the nearest thousand is 3000.
The first ten digits of pi are 3.141592653. If rounded to the nearest billionth, that last digit would be 4 instead of a 3.
The thousandths place is the third digit after the decimal point. 86.255 only has 3 digits after the decimal point so it is already (possibly) rounded to the nearest thousandth.

Just one. The trailing zeros are not significant. * * * * * Not true. Integers with trailing 0s are ambiguous. You cannot differentiate between 500o as a number rounded to the nearest thousand (1 significant digit), or the nearest hundred (2 sig digits), or the nearest ten (3 sig digits) or the nearest unit (4 sig digits).
