The review has the answers but not how to solve them and I cannot figure out how to get the solution on my own. I do have an exam soon so quick answers would be AMAZING.

1. Find the arc length along the circumference of a circle with radius 10 inches and spanned by and angle of 24 Simplify to a reduced fraction in terms of n. Answer: 410/3 inches. 2. (4 pts) A 2 inches long minute hand moves around a circular clock. A. How fast (linear speed in inches/minute) does its tip move? T75 inch/min B. What is its angular speed (in degrees/minute)? 6/min C. Which speed would change if the radius of the clock would change: linear, angular, or both? Why? 3. Consider two runners on circular tracks with radius 55 meters and 60 meters, respectively. If it takes each of them exactly 1.6 minutes to complete one round, how fast is the faster runner running? Answer: About 235.6 meters/min 4. Which point, A or B, on the surface of the Earth has larger linear speed and why? North Pole line of longitude line of latitude equator South Pole 5. State a definition of a reference angle. 6. For each angle 0, mark its reference angle. B 7. State the reference angle for A = 480. Show calculations. Answer: 60 8. Do the following steps referring to the unit circle below: A. Mark the angle A = -480 on a unit circle. B. Draw the special right triangle with the reference angle for 0 = -480. C. Mark the hypotenuse = 1 and mark the other two sides with their corresponding length and appropriate signs according to the quadrant. D. Find the exact value of sin(-480). Answer: sin (-480) = -5 13 wy / -480 9. If csc(O) = -10 and cos()
