The value of Underrot 23pi/4 + Underrot 9 is most nearly equal to which of the following integers? (Please refer to the picture below for the exact version of the question)  Choose one:
A) 16  B) 25  C) 21  D) 31  E) 9
Under root (23pi/4) ~ 18   Under root (9) = 3   Hence, 18+3 = 21 is the approx answer. 21 is the correct answer.
