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
Answer:
15,400 people
Step-by-step explanation:
From the question, we were given the following values:
Land area = 7 miles radius
Population Density = 2200 people per square mile
Step 1
The formula for population density is given as:
Population Density = Number of People ÷ Land Area
Since in the question we were asked to calculate the number of people who love in the region, we can derive that formula from the Population density formula
Population Density = Number of People/ Land Area
So we cross multiply
Hence,
The formula for the number of people = Population density × Land Area
= 2200 people per square mile × 7 mile radius
= 15,400
Hence the Number of People who live in the region to the nearest ten thousand is 15,400 people.
