This is Math methods (Y9), and I want to find the perimeter of this shape, but I was unsuccessful in finding help on the internet.

  1. Do not ping the Moderators, unless someone is breaking the rules.
  2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
  3. Do not ping other members randomly for help.
  4. 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.
  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

So, just find their lengths separately, then add them.

To be fair, it's the only question like this in the textbook, and probably won't be in my test, but I mean, it's better to be safe than sorry.

if you notice

#

this will yeild you a better shape

#

not necessary to do this, but obviously cuts down 60% of the calculation

graceful valve
#

yeah

#

wait so both of them are the same length right?

balmy zodiac
#

both what

#

arcs?

graceful valve
#

yeah.

balmy zodiac
#

obviouslyy

graceful valve
#

yeah mb, i'm like doing 2 things at once so i have to ask more questions

#

and then all i need to do to find those lengths are to do the arc formula to find the length of the arc, and add that to the perimiter of the straight line segments, which should get me my answer. Imma do that, and then come back and let yall know if I solved it tysm yall.

I did exactly what I typed out, Just multiplied the arc length by 4, then aded 8x4, and then ended up getting ≈50.3 + 32, which then ≈82.3
