A clarinet acts as a closed-ended air column. If its bottom note has a frequency of 130 Hz, how long is the column?

This is more a question for physics but here goes:
For a closed tube (i.e., a tube with one open end and one closed end), the equation is given as
LT= 1/4 WL length of tube = 1/4 of wave length
using the speed of sound to find the wave length use these formulas
speed of wave = wave length x frequency
speed of sound = 331.5 +.6TC in meter / sec
Here TC is the temperature in °C and the speed of sound is given in m/s. Set temp to 25 °C.
plan of attack:
find the speed of sound at 25 deg
use speed of sound and given freq to get wave length then divide by 4 to get answer.
