Time to Swing. The period T (time for one complete cycle) of a simple pendulum is realted to the length L (in feet) of the pendulum by the formula 8T^2=(3.142)^2L
8T^2=(3.142)^2(10)
8T^2=(9.870)(10)
98.7 seconds

Is this correct?

I assume you are working with a 10 foot pendulum.

What about the 8T^2?

You only calculated the value of the right side of the expression.

8T^2 = 98.721
T^2 = 12.34
T = 3.512

This was a big help, thank you.
