Okay, it took me about 5 years to come up with this formula. And I think it is right, but I have not proofed it.
So you want to make a barrel or cylinder out of slats of woods. The important thing to know it what degree you want to set your table saw at before making the strips.
One: First you figure out the diameter of your cylinder. Let's say that it is 12"
Now you need to know the total " external width" of the slats you need to cut. So you find the circumference of your desired diameter by using the simple formula. Remember first radius equals half of diameter. Circumference = 2*Pie*radius.
A. So once you get that figure you divide it by the number of slats you want to use to make the barrel.
or.
B. You determine what external width of each slat you want it to be and divide the circumference by the number of slats. For example,you might want your slats to be either 1.5" or 1.75" or 2" wide as you set that setting on the table saw.
TWO:
So, you then need to figure out how to set the angle on the table saw as you rip the boards at the desired width each in B above.
And that is where we find my formula.
Degree = 360/(# of slats x 2)

Five years? That is how long it takes you to do something that should take you 5 minutes to do if you didn't live in a wind tunnel.
