Homework Statement
A metal bar has a length measured to a precision of +-1%, a mass measured to +-2% and a radius masured to +-3%. What would be the % error in the value of the density of the metal in the bar calculated from these?
Homework Equations
V=(pi)r^2h
D=m/v
The Attempt at a Solution
I can calculate the actual density no problem.
However, i was away while we studies calculating with errors and am stuck.
If someone could help me with this problem or recommend a site/book i use to catch up, i'd really appreciate it :).
