Homework Statement
Been given a problem where a force (F) is applied on a circular area (m2). If the percentage uncertainty of the force is 8% and the percentage uncertainty of the radius is 3%, what is the percentage uncertainty of the obtained value pressure?
Homework Equations
I know that pressure equals force over area and to find the area it is πr2. Anyway to work the percentage out?
The Attempt at a Solution
I assume you don't just 'add' the percentage uncertainties in this case. So far see that 8% over π3%2 would be the equation to work this out.
