Question

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)
○ saturn
○ jupiter
○ mars
○ earth

Explanation:

Step1: Calculate actual diameter

Given scale: 1 cm = 10,000 km. Model diameter = 12 cm. So actual diameter = \(12 \times 10,000 = 120,000\) km.

Step2: Recall planet diameters

• Jupiter's diameter is about 139,822 km (close to 120,000 km approximation here).
• Saturn: ~116,464 km (also close, but Jupiter is more massive and often associated with large diameter; the 12 cm model (120,000 km) aligns best with Jupiter's approx diameter when considering typical planet diameter ranges).
• Mars: ~6,779 km.
• Earth: ~12,742 km.

Answer:

Jupiter
