Answer:
247 people per square mile
Explanation:
Population density is people per area
We need to find the area
We are given the radius
We will assume a circular area since we are given radius
A = pi r^2
A = 3.14 * 5^2
A = 3.14 *25
A = 78.5 miles ^2
19400 people
---------------------
78.5 miles ^2
247.133758 people per square mile
Rounding to the nearest person
247 people per square mile
