Question

The diameter, D, of a sphere is 13.6m . Calculate the sphere's volume, V . Use the value 3.14 for π, and round your answer to the nearest tenth.
Which one is it? 280.696239 or 1,316.42197??

Answer 1

280.696239 i think it's that

Answer 2

how many Significant Figures does it have

Answer 3

idk what that is Devilwolf3000

Answer 4

try the answer i put

Answer 5

I cant check it because it's a test!

Answer 6

Significant Figures

Answer 7

lol ik try it

Answer 8

nooooo lol I don't want to get it wrong!

Answer 9

Significant figures are critical when reporting scientific data because they give the reader an idea of how well you could actually measure/report your data. Before looking at a few examples, let's summarize the rules for significant figures.

1) ALL non-zero numbers (1,2,3,4,5,6,7,8,9) are ALWAYS significant.

2) ALL zeroes between non-zero numbers are ALWAYS significant.

3) ALL zeroes which are SIMULTANEOUSLY to the right of the decimal point AND at the end of the number are ALWAYS significant.

4) ALL zeroes which are to the left of a written decimal point and are in a number >= 10 are ALWAYS significant.

A helpful way to check rules 3 and 4 is to write the number in scientific notation. If you can/must get rid of the zeroes, then they are NOT significant.

Examples: How many significant figures are present in the following numbers?

Number # Significant Figures Rule(s)
48,923 5 1
3.967 4 1
900.06 5 1,2,4
0.0004 (= 4 E-4) 1 1,4
8.1000 5 1,3
501.040 6 1,2,3,4
3,000,000 (= 3 E+6) 1 1
10.0 (= 1.00 E+1) 3 1,3,4

This gives you some idea of how to determine the number of significant figures in a single number. To find out how to use this information when performing mathematical operations (addition, subtraction, multiplication, division), see "Significant Figures: Mathematical Operations."

Ummm... Cheating is really not where we want to be, now, is it? Let's close this thread.
