A little math review or preview......

This cedar tree sits in Portland, OR and for the sake of this exercise we are going to assume the tree  is consistently round. The radius of the tree is 17" which makes the diameter ________ and the circumference _________. There is not a branch for the first 40' of the tree which soars to over 100' in total height. My father-in-law is a wood worker and he would love to turn a bedroom closet into a cedar closet. How many linear feet of rough sawn 1" x 6" sized lumber can he get out of the first 40' once he convinces his grandson and granddaughter to have the tree cut down? You also have to remember that a modern 1" x 6" is actually not 1" by 6" but _____________________________. You will also have some waste on the circular portion of the tree. If you really want to add some spice to the project.......pretend that each saw cut takes out 1/8". So, if you are a retired history teacher like me, get out a big piece of butcher paper and get a circle drawn with the proper diameter and starting laying out the most efficient way to slice the 40' trunk of cedar to get the least waste and most linear feet of wood. Dad, Mom, and children of all ages, time to practice your planning skills. Oh, no answer from me, these are simply for some application of math. I'll try and remember to add some additional problems once you see how much wood you will produce.
