The density of the wood of a pine tree is 35 lbs/ft3. the tree is 72 feet high and the diameter is 3 feet. ten percent of the weight of the tree is contained in the branches and foliage. if the trunk of the tree is a right circular cylinder, estimate the weigh of the tree above the ground.
The volume of a cylinder is given by pi*r^2*h where r = radus and height = h
volume = 3.14*1.5*1.5*72=508.68
mass = volume * density
508.68*35=17803.8
10% is branches
90% is tree trunk 90%*17803.8 =16023.42 lbs
