  1. 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.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

The exact area is that because it would be the area under the curve of C (already given) plus the area you need to solve for equaling the area under line l. So it would be the area under line l minus the area under C equaling what you want. The area under C is in the integral, which you understand. Now to solve for the area under line l, plug in for the x- and y- values provided the given theta. Since it is a rectangle, multiply these x and y values and you will get your desired answer. I got pi*sqrt(3)/12 times 2/3, which is what is given in the answer key. Ping me if you need more help.
