Question

The approximate diameters of Saturn and Neptune are listed below:

Saturn: 1.21 x 105 kilometers

Neptune: 4.95 x 104 kilometers

What's the difference between the diameters of the two planets? Express your answer
using either standard notation or scientific notation.

Answer 1

The diameter of Saturn is 71,500 kilometers larger than the diameter of Neptune.

Step-by-step explanation:

The difference between the diameters of Saturn and Neptune can be calculated by subtracting Neptune's diameter from Saturn's diameter.

Saturn's diameter: 1.21 x 105 kilometers
Neptune's diameter: 4.95 x 104 kilometers

The difference in diameters: 1.21 x 105 km - 4.95 x 104 km = (1.21 - 0.495) x 105 km

Which simplifies to: 0.715 x 105 km, or using standard notation: 71,500 kilometers.

Thus, the diameter of Saturn is 71,500 kilometers larger than the diameter of Neptune.
