Question

Find the approximate area of each continent using the percentages given in the circle graph. The area of North America is approximately 220 million km². Show your work.

Answer 1

The approximate areas of each continent based on the percentages given in the circle graph are as follows:

- Africa: 30% (Approximately 660 million km²)

- Asia: 60% (Approximately 1,320 million km²)

- Europe: 10% (Approximately 220 million km²)

Step-by-step explanation:

The given information states that the area of North America is approximately 220 million km². Since North America represents 10% of the total, we can use this percentage to find the total area of the Earth's continents. To find the total area, we can use the formula:

`\[ \text{Total Area} = \frac{\text{Area of North America}}{\text{Percentage of North America}} * 100 \]Substituting the given values:\[ \text{Total Area} = \frac{220 \, \text{million km²}}{10\%} * 100 \]`

Solving this equation gives us the total area of the Earth's continents. Once we have the total area, we can use the given percentages for each continent to find their approximate areas:

- Africa: 30% of the total area

- Asia: 60% of the total area

- Europe: 10% of the total area

These percentages are applied to the calculated total area to find the approximate area of each continent. Therefore, Africa is approximately 660 million km², Asia is approximately 1,320 million km², and Europe is approximately 220 million km².
