Homework Statement
A radius of a sphere is measured to be (6.45 ± 0.27) cm, and the mass is measured to be (1.78 ± 0.09) kg. Determine the density of the sphere in kilograms per cubic meter and the uncertainty in the density.
Homework Equations
Use the following formula to calculate the uncertainty in the density:
Δρ/ρ = Δm/m + 3Δr/r.)
The Attempt at a Solution
I already found the density: 1583.62 kg/m3
I just want to know how to get the uncertainty. I don't know how to use the formula given. i always get a really low number with it.
