Jason designed an arch made of wrought iron for the top of a mall entrance. The 11 segments between the two concentric circles are each 1.25 m long. Find the total length of wrought iron used to make the structure. Round the answer to the nearest meter.
Sorry, this site is not for help on timed exams - be honest! Ask your teacher if you can correct the test for credit if it is really a problem.
btw, you should not use ANY site for timed exams. That is cheating, unless explicitly allowed IN the exam.
That being said, I am more than willing to help you tomorrow, when I assume you will have submitted your test. :)
I guess though, I will offer a hint, because many students here do not even admit to cheating but daily do it. Note that all straight lines are the same, and have to do with the radii of the circle. Also note that the concentric means "same center"
