Finding cubic meters of a tree log

I have a tree log that has a diameter of 426.55mm, the length of the log is 6109mm.
I need to culculate the volume of the log in meters cubed.

The volume of a cylinder is (pi/4)*d²*h
Express the dimensions in meters, d = 0.42655 m, h = 6.109 m

Then V = 0.785 * 0.42655² * 6.109 = 0.873 m³

Where did you get V=0.785?

I have a log of diameter of 0.62m and a length of 2.25 m does that mean my cubic volume is 1.095?

0.785 is (approx) pi/4. You still have to multuiply by diameter squared and length.
