A student creates a scale model of planets where 1 centimeter (cm) is equal to 10,000 kilometers (km). In this model, which planet would have a diameter of approximately 12 cm?(1 point)
Responses
Saturn
Saturn
Jupiter

Mars
Earth
To determine which planet would have a diameter of approximately 12 cm in the scale model, we need to convert the model's scale to actual planetary diameters in kilometers.
According to the scale:
1 cm = 10,000 km
Therefore, a diameter of 12 cm would represent:
12 cm * 10,000 km/cm = 120,000 km
Now, let's look at the actual diameters of the planets mentioned:
- Saturn: about 116,460 km
- Jupiter: about 139,820 km
- Mars: about 6,779 km
- Earth: about 12,742 km
Saturn's actual diameter is closest to 120,000 km, so in the scale model where 1 cm represents 10,000 km, Saturn would have a diameter of approximately 12 cm.
