Question

Use the chart below to answer the questions:

COuld you please explain how to do this please
Country Population
(1997 estimate) Area
(square km)
U.S. 272,648,000 9,364,520
Denmark 5,248,000 42,077
Ghana 18,339,000 237,533


Which of these countries has the greatest population density? Which has the least?

Answer 1

Population density means 'people per sq km'

so make another column and calculate population/area for each country

then choose the largest and smallest in the column for your answers

Answer 2

how would i find the area? Formula?

Answer 3

the area is given in the question

Answer 4

so denmark has the least with only 42,077 and us has the most with 9,364,520

Answer 5

That is the area - you need to calculate the density

\[population density =\frac{ population }{ area}\]

Answer 6

So for US:
Population = 272,648,000
Area = 9,364,520

\[Density = \frac{272,648,000 }{9,364,520 }\]

Work that out, and then do the same for the other 2 countries

Answer 7

so for the us i got 29.1150000214, for denmark i got 124.723720798 and for ghana i got 77.2061145188, also it doesnt tell me to round, so should i

Answer 8

It only asks you to find the highest and lowest density - so you don't need to round


(BUt you should be able to understand that those numbers are unceccessarily long for the sensible answer )

Answer 9

was my answers right?

Answer 10

Did you divide the numbers from the table? it's only simple division - you don't need me to confirm it

Answer 11

ok then, thanks
