205. A wheel has a radius of 5 feet. What is the
minimum number of complete revolutions that the
wheel must make to roll at least 1,000 feet?
206. To measure the length of a hiking trail, a worker
uses a device with a 2-foot-diameter wheel that
counts the number of revolutions the wheel
makes. If the device reads 1,100.5 revolutions
at the end of the trail, how many miles long is the
trail, to the nearest tenth of a mile?
207. Every time the pedals go through a 360° rotation
on a certain bicycle, the tires rotate three times.

longitude and the difference in the latitude of
these cities is 9°, as shown in the accompanying
diagram. If Earth's radius is 3,954 miles, how
many miles north of city K is city H along arc
HK? Round your answer to the nearest tenth
of a mile.
