If you measure the outside measurement of the track wrapped, you have the distance, regardless whether it's circular, hexagonal, or ten-sided. I don't think drive speed accuracy for a 1/6 model is necessary down to millimetres.

The drive sprocket isn't a wheel, it's a hexagon (or whatever)and what matters is not the circumference of the track when it's on the drive sprocket, but the length of that track when it's on the ground (bearing in mind that the track links hinge or bend). The way to find out is to wrap the track round the sprocket, turn the sprocket 1 revolution and note how far forward the sprocket has moved.
