Answer:
And solving for the radius we got:
And replacing the data given we got:
And this value converted to meters is
Step-by-step explanation:
For this case we know the population size and we also know the population density
We can assume that the area is a circle. We also know that the formula for the population density is given by:
Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:
With X the radius of the circle
And then the populationd density become:
And solving for the radius we got:
And replacing the data given we got:
And this value converted to meters is
