Calculate the land area for each city by dividing the population by the population density.
Compare the population of Manila and New York to determine which is greater.
Compare the land area of New York to the land areas of Delhi and Manila.
The population of Manila is greater than the population of New York. T r u e
Explanation
Analyzing the Problem We are given a table with data about four cities: Delhi, Manila, Karachi, and New York. The data includes the city's world rank, population, and population density. We need to determine which of the given conclusions is supported by the data in the table.
Checking Land Areas The first conclusion is: The land areas of Karachi and New York must be very similar in size. To check this, we need to calculate the land area of each city. The formula for land area is: Land Area = Population / Population Density.
Calculating Land Areas Using the formula, we find:
Delhi Land Area = 22,826,000 / 30,400 ≈ 750.86 sq mi
Manila Land Area = 21,241,000 / 38,300 ≈ 554.60 sq mi
Karachi Land Area = 20,877,000 / 67,300 ≈ 310.21 sq mi
New York Land Area = 20,673,000 / 4,600 ≈ 4494.13 sq mi
Comparing Karachi (310.21 sq mi) and New York (4494.13 sq mi), we see that their land areas are not similar. So, the first conclusion is incorrect.
Comparing Populations The second conclusion is: The population of Manila is greater than the population of New York. From the table, we have:
Manila Population = 21,241,000
New York Population = 20,673,000
Since 21,241,000 > 20,673,000, the population of Manila is indeed greater than the population of New York. So, the second conclusion is correct.
Comparing Land Areas Again The third conclusion is: New York has a smaller land area than Delhi or Manila. We already calculated the land areas:
New York Land Area ≈ 4494.13 sq mi
Delhi Land Area ≈ 750.86 sq mi
Manila Land Area ≈ 554.60 sq mi
Since 4494.13 > 750.86 and 4494.13 > 554.60, New York has a larger land area than Delhi and Manila. So, the third conclusion is incorrect.
Final Land Area Comparison The fourth conclusion is: New York has a larger land area than Delhi or Manila. As we saw in the previous step, New York's land area (4494.13 sq mi) is larger than both Delhi's (750.86 sq mi) and Manila's (554.60 sq mi) land areas. So, this conclusion is correct.
Final Answer Based on our analysis, the table supports the conclusion that the population of Manila is greater than the population of New York, and that New York has a larger land area than Delhi or Manila.
Examples
Understanding population density and land area is crucial in urban planning. For instance, knowing these metrics helps city planners determine resource allocation, infrastructure development, and manage urban sprawl. By comparing population and density, planners can assess the need for new housing, transportation systems, and public services, ensuring sustainable and efficient urban growth. This type of analysis is fundamental to creating livable and well-organized cities.
The table supports the conclusion that the population of Manila is greater than the population of New York and that New York has a larger land area than both Delhi and Manila.
