I know alot of you are way smater than me. I am building a birdhouse. It is a cylinder with the circular ends diameter = 6". I want to encase this cylinder with equal pieces of wood each 1.24" in width.
I know the circumference = diameter * Pi = 18.84.
I know that 18.84 / 1.25" = 15 pieces of wood.
How to calculate the angle cut for each of those 15 pieces so they fit snugly together?
I figure since you are not thinking about Empire you can think on this one.

So for four sides 360 / 4 / 2 = 45%, 6 sides 360 / 6 / 2 = 30%
BUT. Don't forget your 6" diameter is the *inside* of the shell so the
wood will be narrower. You need to work out your number of staves based
on the diameter plus twice the thickness or you'll have a gap!

360 / (num of sides) / 2

Whatever happened to figuring it out the old fashioned way? Go ask
your wife!
Or, slightly less old fashioned, draw it up in Pro-E or UG and then
measure it.
But I do concure with Mr. Frost. 360/15/2 = 12 degrees. And the
diameter will be slightly off from 6". If the birds complain, stop
feeding them (or get a cat)
Seriously though, the feeder should have 6 sides on it with a big "a"
pained on it for ag center. Then really screw with your neighbors and
paint "6,-4" on one of the sides
your wife!

12 degrees worked perfectly, just made the last piece slightly larger to fit.

Thanks for the info.
