The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten.
For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
An improvement in the quality of measurement by using better instrument increases the significant figures in result .The significant figures are all digit that are known accurately and one estimated digit. More significant figures mean more greater precision.

If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
The number of significant figures should be equal to the significant figures in the least precise measurement.
370.0 has four significant figures, because the last zero indicates the precision of the number (to 1 decimal place).
There is one significant figure: 1 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 1) are not significant.

No. Stating more significant figures in a quantity doesn't guarantee that the figures are true.
If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
3 significant figures
There are two types of significant figures, measured and exact. Numbers are often rounded to avoid reporting insignificant figures. Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement.
Significant figures indicate the precision of a measurement.
When divided by a calculator 45.67kg/3.42L equals 13.35 kg/L. Of the two quantities the highest common certainty we have is the 3 significant figures from the volume. Therefore the answer would be 13.4 kg/L rounded to three places.
4 significant figures.
The significant figures (also called significant digits) of a number are those digits that carry meaning contributing to it's precision. This includes all digits except:Leading zeros where they serve merely as placeholders indicate the scale of the number.spurious digits introduced, for example, by calculations carried out to greater accuracy than that of the original data, or measurements reported to a greater precision than the equipment supports.
All three of them are significant figures
There are two significant figures: 2 and 0 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 2) are not significant.
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
