Unformatted text preview: 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. Linear Speed Angular Speed Linear Speed and Angular Speed 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....
