Tammy is at the dentist's office waiting on her appointment. She notices that the 6-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 3: How many radians on the unit circle would the minute hand travel from 0° if it were to move 5π inches? Part 4: What is the coordinate point associated with this radian measure?

    use the formula arc length = radius * angle in radians L = rC

    That's what I tried but then I think I am now just over complicating it. So it would be 6(5π)? 30π?

    i think you have it backwards the radian measure of the angle is the arc length divided by the radius

    if the arc length is \(5\pi\) and the radius is \(6\) the the measure of the angle is \[\frac{5\pi}{6}\]

    Oh, I was trying to solve for arc length. Duh. I see it now. Thank you so much!! So with that I can easily find the coordinates based on the unit circle.
