That depends on your goals AND on your measuring capabilities.

The number given of 11254 has five significant figures

It depends upon how you got to the 12, for example: 28.6 - 16.6 = 12.0 Because each of the numbers that was used to get to the 12 had 3 significant figures, you should write the 12 with three significant figures also. However: 29 - 17 = 12 In this case, each of the numbers that was used to get to 12 had only 2 significant figures, so use only 2 significant figures in the 12.

5 of them.

3.774 is to 4 significant figures (count them)

Count the significant figures in each number. Calculate the minimum of these numbers. Do the multiplication Round the product to the LEAST number of significant figures, determined above.

There are 4 significant figures in 6.741.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

4 of them.

yes

For a multiplication or division, you should check how many significant figures each of the factors has, and take the least of them. This is the number of significant figures you should keep in the answer.

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.

Yes. They each have six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.

Count the significant digits in each of the factors, and take the smallest of them.

4 significant figures.Zeros are significant if they are between two non-zero numbers, or if they are "trailing" zeros in a number with a decimal point.Eg.0.000047 = 2 significant figures4.7000 = 5 significant figures

Each of them ... the 2, the 4, the 6, and the 9 ... has one significant figure.

The number 0.0102030 has 6 significant figures. Each of the non-zero numerals (3 of those), the zeros between the non-zero numbers (2), and the zero on the end of the number if it is right of the decimal (1). The significant figures are in bold:0.0102030

I believe you mean significant figures. Take an example. If you measure the length of a table as 1.52 m and its width as 1.46 m, each is measured to the nearest cm, and the values have just 3 significant figures. So the area of the table could be calculated as 1.52 x 1.46 = 2.2192 m2. But as the length could actually be between 1.515 and 1.525m, and similarly for the width, the area of the table could be between 1.515 x 1.455 = 2.2043 m2 and 1.525 x 1.465 = 2.2341 m2. So the answer should be given to 3 significant figures (2.22 m2) as the 4th and 5th figures are not significant. As a general rule, in multiplication and division the number of significant figures given in your answer should be no more than the smallest number of significant figures found in any of the numbers used to do the multiplication (or division). 4.5 x 4.653 x 3.234 = 67.715109 = 68 to 2 sig.figs.

1.060 contains 4 sig figs.

0.0451. 450 has two significant figures, 32.10 and 370.0 each have four.

When a number is written in scientific notation, the digits that do not appear are not significant. The rest are significant figures. For example, when you convert 0.0003102 to scientific notation, it is 3.102 X 10-4. Therefore the zeros before the 3 are not significant.The 3 significant figures implies to all digits around it, regardless of before and after the decimal point. 8.00 has 3 sig.figs. This is because of the 2 zeroes after the decimal point. When you have 30 zeroes after the decimal point, such as 3.000000000000000000000000000000, you have 31 significant figures. 1.23 has 3 sig.figs. This applies to all questions, if needed.The amount of figures given in an answer where you begin with approximates of numbers. The answers should not be more precise than the original measurements. This would lead to a misleading answer, and thus significant figures were created to show an accurate approximation of your answer.The idea of significant figures (sig figs or sf), also called significant digits (sig digs) is a method of expressing error in measurement.The most significant digit is the "first" digit of a number (the left-most non-zero digit). Similarly, the least significant digit is the "last" digit of a number (sometimes, but not always, the right-most digit). A number is called more significant because it carries more weight. In the decimal number system (base 10), the weight of each digit to the left increases by a multiple of 10, and conversely the weight of each digit to the right decreases by a multiple of 10. A similar thing happens in the binary (base 2) number system - see most significant bit.Sometimes the term "significant figures" is used to describe some rules-of-thumb, known as significance arithmetic, which attempt to indicate the propagation of errors in a scientific experiment or in statistics when perfect accuracy is not attainable or not required. Scientific notation is often used when expressing the significant figures in a number.The concept of significant figures originated from measuring a value and then estimating one degree below the limit of the reading; for example, if an object, measured with a ruler marked in millimeters, is known to be between six and seven millimeters and can be seen to be approximately 2/3 of the way between them, an acceptable measurement for it could be 6.6 mm or 6.7 mm, but not 6.666666... mm as a recurring decimal. This rule is based upon the principle of not implying more precision than can be justified when measurements are taken in this manner. Teachers of engineering courses have been known to deduct points when scoring papers if excessive significant figures are given in a final answer.Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.Significant figures (also called significant digits) can also refer to a crude form of error representation based around significant figure rounding.Significant figures are digits that show the number of units in a measurement expressed in decimal notation.

5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
