Question

the approximate diameters of 5 planets are shown in the table below. diameters of selected planets planet diameter (in kilometers) earth 12,800 mars 6,800 saturn 1.2×10^5 uranus 5.1×10^4 neptune 5.0×10^4 which of the following lists shows the planets in order from the least diameter to the greatest diameter? earth, mars, saturn, uranus, neptune saturn, uranus, neptune, mars, earth mars, earth, saturn, uranus, neptune mars, earth, neptune, uranus, saturn

Explanation:

Step1: Write Saturn's diameter in standard form

$1.2\times10^{5}=120000$

Step2: Write Uranus's diameter in standard form

$5.1\times 10^{4}=51000$

Step3: Write Neptune's diameter in standard form

$5.0\times 10^{4}=50000$

Step4: Compare the diameters

$6800<12800<50000<51000<120000$
So Mars < Earth < Neptune < Uranus < Saturn

Answer:

Mars, Earth, Neptune, Uranus, Saturn
