The population density in the United States is D = 92.1 people/mi^2
<h3>
</h3><h3>
How to get the population density?</h3>
To get the population density, we need to take the quotient between the total number of people and the area.
In this case, we know that the total population is 325.7 million, and the area of the United States is 3,535,932 mi^2
Then the population density:
D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2
And we know that 1 million = 1,000,000 = 1*10⁶
Then:
9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2
This means that in each square mile in the United States, there are around 92.1 people.

For this case we have that by definition, the volume of a cone is given by:
Where:
r: It is the radius of the cone
h: It is the height of the cone
According to the statement data we have:
Substituting in the formula:
We cleared the radius:
We choose the positive value:
We round and we have that the radius of the cone is:
