Population density is population divided by area. So
City: 1,503,049 people / 181.5 km^2 = 8281.262 = 8281 people/km^2
I think you have more questions, and these might be the answers to those questions too.
Watering hole. Same thing, population divide by area. Only gotcha is the area needs to be calculated. Using A = pi r^2, you get
3.14 * (34 km)^2 = 3629.84 km^2
32/3629.84 = 0.008816 = 0 antelopes/km
Chunk of mahogany wood.
Take the volume and multiply by the density. So
1728 cm^3 * 0.71 g/cm^3 = 1226.88 g
Gold bar.
Same thing. Volume multiplied by density. So
51.8 cm^3 * 19.3 g/cm^3 = 999.74 g
And finally, the sugar maple. This one is slightly trickier. You first need to calculate the volume of the block of wood. So divide the mass by the density.
82.8 g / 0.69 g/cm^3 = 120 cm^3
Now you know the length and width are 5x4 = 20 cm^2. So calculate the height by dividing the volume by 20 cm^2. So
120 cm^3 / 20 cm^2 = 6 cm.
Thanks!
A city with a population of 1,503,049 and land area of 181. 5 km² has a population density of approximately 8,281 People/km².
Population density simply refers to the total number of persons that are living in a population per unit area.
Mathematically, population density can be calculated by using this formula:
Population density = Population size/land area
Substituting the given parameters into the formula, we have;
Population density = 1,503,049/181.5
Population density = 8,281 People/km².
