  1. 1. Section 6.1 Angles and Their Measure
  2. 7. OBJECTIVE 1
  3. 10. Radians
  4. 11. OBJECTIVE 2
  5. 14. Find the length of the arc of a circle of radius 4 meters subtended by a central angle of 0.5 radian.
  6. 15. OBJECTIVE 3
  7. 17. (a) 80 ° (b) 140° (c) -30° (d) 100°
  8. 21. OBJECTIVE 4
  9. 23. Find the area of the sector of a circle of radius 5 feet formed by an angle of 40 °. Round the answer to two decimal places.
  10. 24. OBJECTIVE 5
  11. 25. Linear Speed Angular Speed
  12. 26. Earth rotates on an axis through its poles. The distance from the axis to a location on Earth 40 ° north latitude is about 3033.5 miles. Therefore, a location on Earth at 40° north latitude is spinning on a circle of radius 3033.5 miles. Compute the linear speed on the surface of Earth at 40° north latitude.
