Once trees grow to a certain height, the trunks quit growing taller and only grow thicker. The forest rangers want to calculate the diameter of the cross-section of some trees in order to estimate how much they grew in the past year. They measured the circumference of the trees, and one of them was 3 meters. Calculate the diameter of the tree.
