- Do not ping the Moderators, unless someone is breaking the rules.
- Do not ping the Helper Moderators, unless there is a conflict between helpers.
- Do not ping other members randomly for help.
- Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
- Wait patiently for a helper to come along.
- If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:
+close
Feel free to nominate the person for helper of the week in #helper-nominations
If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Notice that $S=r\theta$, where $\theta$ is in radians, $r$ is the radius, and $S$ is the length of the arc.

Also notice that the area of a sector is $A=\frac12r^2\theta$

Well the questions with sectors and arcs

degrees not radians
the question is askig for it in degrees
@lost axle do you know the formula for the length of an arc (in degrees)
$\frac{\theta}{360} \times 2 \pi r$

tardy thicket
we know what r is and we know what the arc length is
so we plug in the numbers
$\implies \frac{\theta}{360} \times 14 \pi = 13.7$

**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.
**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).

Oh, and for the last one, note Thales’ Theorem (i.e., the triangles you’re dealing with are right triangles).

Yeah. Pretty well known.
