This is a model of a core sample taken from a tree, cut down in 2014. You can find the age of the tree by counting all the annual rings. Remember, each space between two grooves is one annual ring and represents one year of growth. Do not count the pith or bark as these are not annual rings. How old was the tree when it was cut down?(if you get a slightly different number than the correct one indicated below, it is ok, the lines can make your eyes criss-cross) 47 85 22 67 64
