Answer 1

To order the planets based on their diameters from smallest to largest, we can first list the given diameters:

• Mercury: \( 4.87 \times 10^3 \) kilometers (4,870 km)
• Mars: \( 6.79 \times 10^3 \) kilometers (6,790 km)
• Earth: \( 1.28 \times 10^4 \) kilometers (12,800 km)
• Venus: \( 1.21 \times 10^4 \) kilometers (12,100 km)

Now, we will compare the values:

1. Mercury: \( 4,870 \) km
2. Mars: \( 6,790 \) km
3. Venus: \( 12,100 \) km
4. Earth: \( 12,800 \) km

Now, ordering them from smallest to largest diameter:

1. Mercury: \( 4.87 \times 10^3 \) km
2. Mars: \( 6.79 \times 10^3 \) km
3. Venus: \( 1.21 \times 10^4 \) km
4. Earth: \( 1.28 \times 10^4 \) km

Thus, the order is:

• Mercury
• Mars
• Venus
• Earth

So the correct order from smallest to largest diameter is:

• Mercury
• Mars
• Venus
• Earth
