# I need to extract a polynomial equation from results

Posted on 2014-09-29

I have a table of values that provide volume of a cone based on a diameter measurement at the 1.3 meter height mark (volume of an evergreen tree). The creator of the table is long gone and the equation used is too. I do not have the skills to rebuild it and hope a math expert can do it for me and help solve my dilemma.

I do not have a lot to go on so some 'guess work' may be involved.

Here is a list of what I have: Diameter in centimeters and volume in cubic meters. What do I do to expand/extrapolate to 62 cm diameter to get a somewhat accurate volume?

d(cm) vol(m3)

10 0.013

12 0.027

14 0.044

16 0.064

18 0.089

20 0.118

22 0.153

24 0.193

26 0.239

28 0.290

30 0.348

32 0.416

34 0.488

36 0.572

38 0.660

40 0.761

42 0.866

44 0.980

46 1.103
