A cylindrical tree trunk is 14 yards high from the ground up to the lowest branch, and it measures 4 yards around. What is the volume of wood in this section of the trunk?
The volume of the cylindrical figure is given by: V=πr^2h Given that the circumference of the figure is 4 yds, the radius will be: C=2πr 4=2πr hence; r=4/(2π) r=0.64 yds
Therefore the volume of the cylinder will be: V=π*0.64^2*14 =17.83 cubic yards
