**1. 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.

**2. Homework Equations**

Use the following formula to calculate the uncertainty in the density:

Δρ/ρ = Δm/m + 3Δr/r.)

**3. 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.
