Question

What is the percent uncertainity for the measurement given as 1.57 m^2

Answer 1

that's the exact question? i'm not sure what it's asking

Answer 2

yes, thats the question it gave me

Answer 3

do you mean 1,57m^2 + or - 0,01 m^2 ?
if that is the case then uncertainty percentage is
0,01/1,57 *100%=0,64%

Answer 4

I agree! And then \(1.57 \pm .637\%\) (I added one significant figure to match the "\(1.57\)") is called "relative error."

Answer 5

Or "percent uncertainty."
