You measure the radius of a sphere as (6.45 ± 0.30) cm, and you measure its mass as (1.79 ± 0.08) kg. What is the density and uncertainty in the density of the sphere, in kilograms per cubic meter?

Explanation:

Given that,

The radius of a sphere is (6.45 ± 0.30) cm

Mass of the sphere is (1.79 ± 0.08) kg

Density = mass/volume

For sphere,

We can find the uncertainty in volume as follows :

Uncertainty in mass,

Now, the uncertainty in density of sphere is given by :

Hence, the density pf the sphere is

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
