Answer:
Approximately 338,000 people live in that area.
Step-by-step explanation:
In order to solve this problem we first need to find the area of the region, since it's delimited by a 7 miles radius, then we can assume it's a circular region. The area of the circle can be calculated by the following formula:
area = pi*r² = 3.14*(7)² = 153.86 miles²
Since the region has a density of 2200 people per square mile and the density is given by the formula:
density = number of people / area
We can find the number of people living in the region by doing:
number of people = density*area
Applying the data from the problem:
number of people = 2200*(153.86) = 338,492 people
