The mean radius of earth is 6371 kilometers and the the mean radius of earth's moon is 1737.5 kilometers. What is is the approximate difference in the mean circumferences , in kilometers , of the earth's and earth's moon ? Round your answer to the nearest tenth of a kilometer

the correct answer is.

29,098.4 kilometers

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
