The formula given in the question is not important for finding the answer. We just need to look at the given choices to see which one gives the radius of a tree that produces 150 board-feet of lumber. 
Choice A, B, and D all have different hexadecimal values at the end of the string, meaning they correspond to different calculations, so they can be eliminated. 
Choice C has the same hexadecimal value as given in the formula in the question, but with a different value for r. Therefore, r such that 11eb69ff_fe80_9ac2_af94_a998715526f9_TB8190_11 is the correct answer.
