Actually the arc length .
Your angle is correct but you should recalculate s using the correct formula.
A water irrigation arm 500 meters long rotates around a pivot P once every day. How far does the tip of the arm travel in one minute? to the nearest minute.
so this is how I had solved it
s=1/2 0r^2
- 1/2 *2Pi/1440*500^2
i chose 2Pi/1440 because that is how many minutes are in a day. the answer that I get is 5140cm any help would be nice thank you
