# Diameter of a Tree#

## Question Text#

It has been reported (Journal of Plant Studies) that the diameters of trees ($$d$$) are proportional to their height ($$h$$) as the $$2/3$$ scaling exponent, $$d \propto h^{2/3}$$. If the diameter of a 6.05 $$m$$ tree is 36 $$cm$$, what is your prediction for the diameter of a 20.9 $$m$$ tree in $$cm$$?

Please enter in a numeric value in $$m$$.
