Answer:
28.4253408071... ft
Step-by-step explanation:
If you are saying that the diameter is the hypotenuse of the triangle, then we can use Pythagora's theorem to solve for it:
[tex]a^2+b^2=c^2\\18^2+22^2=c^2\\324+484=c^2\\808=c^2\\28.4253408071...=c[/tex]
If the question doesn't mention rounding, then that's our answer.
