Question

If a tree is 4 years old and has a trunk diameter of 27mm. What's the relationship between the diameter and age, what's the age when diameter is 276mm​

Answer 1

Assuming that the relationship is linear, we can write

d=k.a

27=k.4

k=27/4

d=276

276=(27/4)a

a=276×4/27=92×4/9=41 approximately
