The period of a pendulum is the time it takes for the pendulum to make one full​ back-and-forth swing. The period of a pendulum depends on the length of the pendulum. The formula for the period​ P, in​ seconds, is Upper P equals 2 pi StartRoot StartFraction Upper L Over 32 EndFraction EndRootP=2π L 32​, where L is the length of the pendulum in feet. Find the period of a pendulum whose length is one eightteenth 1 18 ft. Give an exact answer and a​ two-decimal-place approximation.
