Question

Find the distance that the earth travels in seven days in its path around the sun. Assume that a year has 365 days and that the path of the earth around the sun is a circle of radius 93 million miles. [The path of the earth around the sun is actually an ellipse with the sun at one focus (see Section 10.2). This ellipse, however, has very small eccentricity, so it is nearly circular.] (Round your answer to one decimal place.)

Answer 1

find the circumference of the earth:
2π(93 million) = ....

multiply that by 7/365

Answer 2

1.6 million miles
