Homework Statement


The density of a cylinder is calculated from the following data:

mass m= (9.1±1.1)g , diameter d = (2.8±0.2) cm , and height H= (4.1±0.6) cm.

The error on the density, before rounding, is ( in g /cm3 )

Yes, well, I have the impression Subo wasn't able to finish his/her post ? There is no question and there are no equations, nor is there an attempt at solution. All very much against PF rules ! Subo: read the guidelines once more, please !

Apart from this rant, I post because I want to know if Subo is used to add errors linearly or quadratically. Covenant in Georgia sticks to linear addition which is very pessimistic. They also have to wriggle to make plausible that it does help to take more measurements and then average, in spite of their pessimistic rule 1.
