Suppose that the volumes of four stars in the Milky Way are 2.7 × 10^18 km^3, 6.9 × 10^12 km^3, 2.2 × 10^12 km^3, and 4.9 × 10^21 km^3. What is the order of the stars from least to greatest volume?

Answer 1

To determine the order of the stars from least to greatest volume, we need to compare their volumes.

1. 6.9 × 10^12 km^3
2. 2.2 × 10^12 km^3
3. 2.7 × 10^18 km^3
4. 4.9 × 10^21 km^3

Therefore, the order of the stars from least to greatest volume is:

2.2 × 10^12 km^3, 6.9 × 10^12 km^3, 2.7 × 10^18 km^3, 4.9 × 10^21 km^3.
