4. A customer wants to make a teepee in his backyard for his children. He plans to use lengths of PVC plumbing pipe for the supports on the teepee, and he wants the teepee to be 12 feet across and 8 feet tall (see figure). How long should the pieces of PVC plumbing pipe be?
Answer by richwmiller(17219)   (Show Source):
You can put this solution on YOUR website! assuming the teepee is cone shaped, then we are dealing with a right triangle with one leg 8 feet and the other is the radius 6 feet
this is a classic 3,4,5 triangle so the hypotenuse is 10 feet
a^2+b^2=c^2
8^2+6^2=c^2 where a=8 and b=6 and c=10
so the support poles need to be over 10 feet to meet and intertwine at the center.
I recommend an additional two feet for the supports
I recommend against using pvc for the supports if a fire is planned in the teepee.
I suspect wooden poles might come out cheaper and stronger than the pvc
and would be more in keeping with the ancestry of the teepee.
