A customer wants to make a teepee in his back yard 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. How long should the pieces of PVC plumbing pipe be?

Answer 1

Use the Pythagorean Theorem:
a^2 + b^2 = c^2

6^2 + 8*2 = c^2

Answer 2

6^2 + 8^2 = c^2
