10F-68

[sidius]

Has anyone found a problem with 10F-68?
I can't seem to get it to solve. This problem is identical to 06B-37 and 10G-67,
and I get both of those to work perfectly with correct solutions. However, it seems
like the numbers used in the 10F version of the problem make it impossible. I get
hung up at the beginning of the problem.

5 meters floss - .085 meters = 4.92
4.92 / 2 = 2.46
(on the other two variations of this problem, I have a small decimal # at this point)
sin(1/r) = (2.46/r) using my TI89 solver to solve for r
Here is where I run into the problem. The 10F won't solve using the numbers given, whereas the
the 06 and 10G versions work perfectly.

Does anyone have any suggestions or ideas?
Thanks!

Thanks for catching that!
Solving for r now, I get 2.61. However, I'm still not getting the correct solution.
What do you suggest doing from this point? The way I worked the 10G and 06E
version of this problem isn't translating.
