It's easy to measure the circumference of a tree's trunk, but not so easy to measure its height. Foresters developed a model for ponderosa pines that they use to predict the tree's height (in feet) from the circumference of its trunk (in inches): ln = -1.2 + 1.4(ln C).  A lumberjack finds a tree with a circumference of 60"; how tall does this model estimate the tree to be?
