In the following equation T=2π√L/32 l stands for the length of the string in feet. Convert your 5 string lengths into feet by dividing by 12 (12 inches = 1 foot). Then, substitute each of these values into the given equation and solve for T (time for one period). Use 3.14 for π. 8 sec 6 sec 5 sec 6 sec 7 sec

    What 5 string lengths? I only see time measurements?

    So you have already converted them to feet correctly, I will assume.

    Do I have the formula right?

    Is it: \[T=\frac{2\pi \sqrt{L}}{32}`or` 2\pi \sqrt{\frac{L}{32}}\]

    So did you get 1.36 seconds for your first answer?

    You can actually take \[\frac{2\pi}{\sqrt{32}}=\frac{6.28}{5.66}=1.11\]

    and multiply each of your string lengths by that constant to get the time

    so what would the second one be ?
