• 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.
• 24. OBJECTIVE 5
• 25. Linear Speed Angular Speed
• 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.
