The radius of a solid sphere is measured to be (6.45 ± 0.25) cm, and its mass is measured to be (1.81 ± 0.07) kg. Determine the density of the sphere in kilograms per cubic meter and the uncertainty in the density. (Use the correct number of significant figures. Use the following formula to calculate the uncertainty in the density: Δρ ρ = Δm m + 3Δr r .)
