Sickly

Is there a formula for finding the length of a coil after wire that has been wrapped around a cylindrical core?

Since that doesn't make much sense, how about an example?

Let's say you have 20ft of 12 gauge wire, and you coiled it around a cylindrical core with a diameter of 2cm; what would be the length of the coil (i.e., how much of the length of the core would it cover)?

Is A Message From Earth viewable anywhere or is it being kept under wraps until 2029?

My video (but more importantly, audio) quality drops like a stone when I drag a clip from my collections to the timeline. Is there any particular reason for this? Or does there happen to be a way to export the collections unaltered as a video?

Diagnose me! A few weeks ago, once fall really started to hit my backyard, my appetite began to change. I'm eating less, in both amount and variety.

Occasionally, I start to get a small itch. Ignorable, but then it begins to spread until suddenly I'm doubling over in pain and itching most everywhere above my waist for about 25 - 45 seconds. This generally follows a little after a sudden change in exertion. I normally sit around, but if I suddenly start acting up and around, I'll burst into itching. No rash left from itching. This started about the same time last year and continued into mid-early spring.

Lastly, I have mild insomnia and chronic headaches ranging from a little congestion to a small migraine.

Any diagnostic types getting any ideas?
