If a tree grows 3/8 inches a year if the diameter is 12 inches how old is the tree in years

32 years

Step-by-step explanation:

From the question we have;

Rate of growth of a tree; 3/8 inches per year Current diameter of the tree is 12 inches

We are required to determine the age of the tree;

To determine the age of the tree we will divide the diameter of the tree by the annual rate of growth. That is;

Age of the tree = 12 inches : 3/8 inches per year

= 32 years

Thus, the tree is 32 years old
