all parts. Make answers bold. For Exercises #6-7, a bug sits on the end of a fan blade as the blade rotates in a counter-clockwise direction. The bug is 2.6 feet from the center of the fan and is located at the 3 o'clock position as the blade begins to turn. *6. a. If the bug travels 5.2 feet around the circumference of the circle from the 3 o'clock position, what angle measure (in radians) has the fan blade swept out? b. If the bug travels 11.7 feet around the circumference of the circle from the 3 o'clock position, what angle measure (in radians) has the fan blade swept out? c. Express the angle measure 0 (in radians) swept out by the fan blade in terms of the are length traveled by the bugs and the circle's radius r (both measured in feet). d. If 0 remains the same and the radius r of the fan doubles, how will the are length s change
