Could anyone help for Calculus 2

[stable socket]

I have a homework assigned to me and it was supposed to be a group work but 2 of the members have not done their work while another member and me have done our part but the work is graded all together. I need help with the third question if anyone is adept at calculus 2 or can use any softwares online that they may know of that can help solve this. If you can help it would be well appreciated!

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. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

I guess you need the surface of a "cut sphere". It's 2.pi.r.h or here 2.pi.16.9 cm², its given by an integral

So your volume isapproximately S*0.04 cm³

U can find the integral on this page https://en.wikipedia.org/wiki/Spherical_cap
and i can explain it if u want (im bad for type formula in latex)
