Question

About 70,000 people live in a 6-mile radius of a city's town hall. Find the population density in people per square mile. Round your answer to the nearest whole number.

The population density is about _
people per square mile.

Answer 1

The population density is 618.93 per square mile.

Explanation:

It is given that,

No. of people, N = 70,000

The radius of a city's town hall, r = 6 miles

We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,

`P=(N)/(A)\\\\P=(N)/(\pi r^2)\\\\P=(70000)/(\pi (6)^2)\\\\P=618.93\ \text{per square mile}`

So, the population density is 618.93 per square mile.
