What is the differences between a significant figure and decimal place?
A decminal place is simply the number of digits to the right of the decimal in a number. For instance, 37.5834 has four decimal places. In contrast, a significant figure is the number of digits on either side of the decimal place that can be counted as accurate in a calculation. Significant figures are used to determine how accurate a calculation is based on how accurate the measurements are. Significant figures are determined by counting the number of significant figures in the numbers given in a problem (usually in chemistry or physics) then using the lowest count found. Here's an example: "calculate the average velocity of a car that has travelled 45 km in 60 minutes." The number "45" has two significant figures while the number "60" has one significant figure. Therefore, when calculating the velocity (45/60), the answer can have only one significant figure: 0.8 km/min. However, if the time was written as "60.0" minutes, then this number would have three significant figures and the answer could have two significant figures (0.75 km/min) because the number "45" had two significant figures.
What is the number of significant figures in 546 km?
3 of them.
The number of significant figures is the measurement 170.040 km is?
170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
How do you convert km to meters?
As a km is 1000 meters, you would divide the number of meters by 1000.DANDivide the number of metres by 1,000. The answer is the number of km.
What is the number between 56000000 km to 399000000 km?
171,500,000 km
Express the sum of 4444 km and 333 km using the correct number of significant digits?
4,777 km
Express the sum of 1111 km and 222 km using the correct number of significant digits?
The sum is: 1333 km
What is 8 miles in a km?
1 km = 0.6214 miles 8 miles ( 1km/0.6214 miles) = 12.8741551 km which according to the number of significant digits will round up to 13 km

What is the Area of a disk with a radius of 112.7 km?
If the disk is circular, the area of one circular face is 112.72 X pi = 3.990 X 104 square kilometers, to the justified number of significant digits.
How many feet is 225 km?
225 kilometers is about 738,189 feet.
How many kilometers are there in 225 miles?
225 mi. = 362.102 km
What is the purpose for leaving decimal values at the end of a number?
The may give additional precision or may be indicators of the number of significant digits in the calculation. As an example of the latter, 5.000 kilometres is, at first sight, no different from 5 km. But, 5 km could represent any length from 4.5 to 5.5 km (rounded to the nearest integer). Whereas 5.000 km can only range from 4.995 to 5.005 km. This difference is important for error analysis.
How many miles is 225 kilometers?
1 mile = 1.6 km 2.25 mile = 2.25 miles x 1.6 km/mile = 3.6 km
How do you round 12.555km to four significant figures?
All of those figures are significant. If you want to round it to 2 sig figs, that would be 13.
Indicate the number of significant figures in each what measured qualities 3.774 km?
3.774 is to 4 significant figures (count them)
