To find which planet would have a diameter of approximately 12 cm in the scale model, we need to scale the actual diameter of the planets by the given ratio.
Since 1 centimeter in the model represents 10,000 kilometers in real life, we can set up the following proportion:
1 cm = 10,000 km
12 cm = x km [We're trying to find the diameter in km of the planet that corresponds to 12 cm in the model]
To find x, we can cross multiply and solve for x:
12 cm * 10,000 km = x km
120,000 km = x km
Therefore, the planet that would have a diameter of approximately 12 cm is Earth.
