Ms. Garcia's science students are studying scale models. For her science project, Sarah has decided to make a scale model of the solar system. Sarah conducted some research to help her with the diameters of the planets and Sun in her model and found the table you see above. Ms. Garcia has instructed her students that a model of the solar system MUST include a Sun with a diameter of 1 meter. What would be the diameter of Sarah's Earth if the Sun is this size?

B 1.09 cm1.09 cm
C 9.2 cm9.2 cm
D 109 cm
To find the diameter of Sarah's Earth in her scale model, we need to compare the diameter of the real Sun with the diameter of the Sun in the model.
According to the information given, the real Sun has a diameter of 1 meter, and we want to find the diameter of Sarah's Earth. We can use the scale model to find this by setting up a proportion:
1 meter (real Sun) = x (diameter of Sarah's Earth)
1 meter (diameter of the real Sun) = 1 (size of the Sun in the model)
Cross-multiplying, we get:
1 * x = 1 * 1
x = 1
Therefore, the diameter of Sarah's Earth in her scale model would also be 1 meter.
A possible error in the question prompt could be that the diameter of Sarah's Earth in the scale model should be provided in centimeters rather than meters. However, based on the given options, there is no correct answer.
