In this activity, students are given the girth and height of 10 National Champion giant trees and asked to determine which of the trees is large enough for a car to drive through. The activity, from the Figure This! list of 80 math challenges, also asks students to apply what they have learned to estimate the height of a tree in their neighborhood. It suggests that the student make a table to relate information about tree girth, circumference, and diameter to help determine which giant trees are big enough for a car to drive through. The importance of measurement formulas to careers in biology, construction, and publishing is noted. The page features links to a solution hint, the solution, related math questions, and resources for learning more about trees. Copyright 2005 Eisenhower National Clearinghouse
