The significant figure could be the 3 as it is gives how big the number is.
If you want how many significant figures there are, then it could be:
* 4: in scientific notation the number is 3.0280 x 10^3 = 3.028 x 10^3 - removing the trailing zero (to leave 4 figures in the mantissa) has had no effect on the value of the number; or
* 5: normally trailing zeros after a decimal point are not written, so in writing point zero (.0) it is assumed to have some significance, eg the number was rounded to 1 decimal place or 5 significant figures.
