To determine which planet would have a diameter of approximately 12 cm in the scale model, we need to find the actual diameter of each planet and convert it to centimeters using the given scale.
- Jupiter has a diameter of approximately 139,820 km. Using the scale, its diameter in the model would be 139,820 km ÷ 10,000 km/cm = 13.982 cm, which is not approximately 12 cm.
- Earth has a diameter of approximately 12,742 km. Using the scale, its diameter in the model would be 12,742 km ÷ 10,000 km/cm = 1.2742 cm, which is much smaller than 12 cm.
- Saturn has a diameter of approximately 116,460 km. Using the scale, its diameter in the model would be 116,460 km ÷ 10,000 km/cm = 11.646 cm, which is approximately 12 cm.
- Mars has a diameter of approximately 6,779 km. Using the scale, its diameter in the model would be 6,779 km ÷ 10,000 km/cm = 0.6779 cm, which is much smaller than 12 cm.
Thus, in the scale model, Saturn would have a diameter of approximately 12 cm.
