The table shows the diameters of three planets:

planet diameter (kilometers)
neptune 4.9 ⋅ 104
saturn 1.2 ⋅ 105
uranus 5.1 ⋅ 104

order the planets from greatest to least diameter.

Saturn > Uranus > Neptune.

Step-by-step explanation:

The diameters of three planets are given in kilometers.

Neptune = 4.9 × 10⁴

Saturn = 1.2 × 10⁵

Uranus = 5.1 × 10⁴

Now we have to calculate all the diameters.

Neptune = 4.9 × 10⁴ =  (4.9 × 10 × 10 × 10 × 10) = 49,000 km

Saturn = 1.2 × 10⁵ =  (1.2 × 10 × 10 × 10 × 10 × 10) = 120,000 km

Uranus = 5.1 × 10⁴ = (5.1 × 10 × 10 × 10 × 10) = 51,000 km

The order of the planets from greatest to least will be

Saturn > Uranus > Neptune.
