To find the population density we need to divide population by area then live on:
[tex]density= \frac{population}{area} [/tex]
The given number live in a circular place. Area is given by formula:
[tex]A= r^{2} \pi [/tex]
Where r is radius
Now we have:
[tex]density= \frac{650000}{ 6^{2} \pi } =\frac{650000}{ 36 \pi }=5747.26[/tex]
The population density is 5747.26 people per square mile.
