    Are we supposed to get an exact answer or an aproximation?

    If that is the case, then to what number does [2*π*√(1/32)] approximate? For each of the four problems, you can set that approximation equal to each of the 4 given values of T.

    What did you get? I have my approximation ready to reveal. In exact terms that product is the following: pi/[2√2]. But, we're doing approximations.

    Crank this out in your calculator: [2*π*√(1/32)]

    In the following equation 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. Record these new measurements in the chart below. the number one above 32 is an "I"

    I know you can approximate this: [2*π*√(1/32)] 2* 3.14159 * .17678 = ? @miah Multiply those numbers. You can use the calculator on your neck.

    If all else fails, go to Google.com and enter "2* 3.14159 * .17678=" in the search box.

    but its an "L" not a 1
