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
Added by Sandra T.
Step 1
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. For Earth, C = 2π(6371) ≈ 40,075 kilometers For Moon, C = 2π(1737.5) ≈ 10,917 kilometers Show more…
