The diameter of the Earth is approximately 7920 miles. Given that the circumference of a circle is _ times its diameter, which statemnt best describles the length of a trip from Washington to Madagascar that is approximately 8600 miles long?
Your question is lacking the statements. However, I can guess the question is asking how far is 8600 miles in relation to the circumference. What is PI*diameter?
One knows that there are 360 degrees in the circle, so to Madagascar it must be near 360*8600/(PI*diameter) degrees,
