Answer:
2291
Step-by-step explanation:
Given: Radius of a city's town hall is equal to 5-mile and about 180,000 people live in a city's town hall
To find: population density per square mile
Solution:
Population density refers to the number of people per unit of area.
Let r denotes radius of the town hall = 5 miles
Area of the town hall = [tex]\pi r^2=\pi (5)^2=25\,\pi[/tex] square miles
Population density per square mile = Population of a city's town hall/area of the town hall = 2290.9 [tex]\approx 2291[/tex]
