Circletown's limits form a perfectly circular shape. It has a population of 20000 and a population density of 480 people per square kilometer.
What is Circletown's radius?

r = 3.64 km

Step-by-step explanation:

Given the following information:

=> The area of the town is:

= Total population / population density per square kilometer

As we know, the formula used to find the area of a circle is:

A = π

In this situation, we already knew the area of the town

<=> A = π  = 41.776

<=> = 41.776  / 3.14

<=> r = 3.64 km

So the radius of the town is 3.64 km
