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
