Calculate (a) the area and (b) the circumference of the circle, and give the uncertainty in each value. 13. A fisherman catches two striped bass. The smaller of the two has a measured length of 93.46 cm (two decimal places, four significant figures), and the larger fish has a measured length of 135.3 cm (one decimal place, four significant ...

Significant Figures (Digits) ... no matter that the calculator displays 8 or 10 or more. 2. Scientific Notation and Significant Digits. The uncertainty in a numerical value may be expressed in terms of a tolerance, as . Alternatively, the uncertainty can be shown in scientific notation simply by the number of digits displayed in the mantissa.

This product has only three significant figures because one of the factors (0.304 cm) has only three significant figures, therefore the product can have only three. Another example: 0.1700 g ÷ 8.50 L. The calculator display of 0.02 g/L, while numerically correct, leaves the impression that the answer is not known with much certainty.

This (5) is the first digit which is affected by the uncertainty, so we have 3 significant figures. Even if a pocket calculator gave us more figures on its display, it would not make sense to use them –i.e. WRONG Too many digits, not all significant. Should not be quoted as …

Example: 0.304 cm x 73.84168 cm. The calculator displays 22.447871. A more reasonable answer is 22.4 cm. This product has only three significant figures because one of the factors (0.304 cm) has only three significant figures, therefore the product can have only three. Another example: 0.1700 g ÷ 8.50 L.

Significant figures are all the digits of a measurement that are known for certain plus one that is estimated. When measurements are used in calculations, the resulting answers cannot have a greater precision than the crudest instrument (the one with the least precision) used to take the measurements.
