A log is 6 meters long, 16 cm in diameter, a total of 150. How many cubic meters is there? How to calculate

The diameter is 16 cm (16 cm), and the radius is 0.08 M
Log bottom area = 3.14x0.08x0.08 = 0.020096 M2
Volume of cylinder = bottom area x height = 0.020096 X6 = 0.120576 M3
150 is 0.120576x150 = 18.0864m3
If it is an approximation, 18 cubic meters is OK
