    Need help bad

    Hey guys I am brand new here. I am a 15 year old currently in 10th grade of high school. I am in geometry but some parts are just really hard about it. I cannot afford a tutor, and the way my teacher explains things is just really confusing. She just gave us a large worksheet with problems that I need some help with. I am not giving all the numbers because the ones i left out, i have already completed. If you could just put your answer next to a number that would be awesome. Thanks so much for all your help

    Sorry, but what you're asking for here is completely unreasonable.

    The purpose of MHF is not to do your homework. Most of these questions can be done by simple substitution into the relevant mensuration formulae that you will find in your textbook.

    You can re-post two or three of the ones that you're absolutely stuck on and have no idea how to do.
