How do we compute the age of a living tree ?

Explanation

To estimate the age of a living tree, following steps are required
(i) Measure the circumference of the tree trunk ( at about 4.5 feet above the ground ).
(ii) Calculate the diameter of the trunk. This is done by dividing the circumference by 3.14 Divide this ( i.e., diameter ) by 2 to get the radius.
(iii) Determine the growth factor. A tree's growth factor is the measurment of the width it gains annually. The tree's growth factor can be seen from the data available or by measuring the rings of a dead tree from the same species.
(iv) Multiply the diameter and the tree species average growth factor and the so done calculating suggest the approximate age of the tree in years.
