Question 293234: I need help find the answer to this problem: "The time that a pendulum of a grandfather clock takes to swing back and forth one cycle is the period of the pendulum. The formula for finding the period T in seconds is T=2(pi)(radical sign)L(over)32, where L is the length of the pendulum in feet. Find the period of a pendulum that is 8 feet long. Write your answer in terms of pi." I understand I have to substitute 8 for L, but I'm not sure where to go from there and how to make my answer in terms of pi.

.
T=2(pi)(radical sign)L(over)32, where L is the length of the pendulum in feet
.
T+=+2%28pi%29sqrt%28L%2F32%29
Then, they said L = 8 feet:
.
T+=+2%28pi%29sqrt%288%2F32%29
T+=+2%28pi%29sqrt%281%2F4%29
T+=+2%28pi%29%281%2F2%29
T+=+pi secs

T=2*pi*sqrt(L/32)
T=2*pi*sqrt(8/32)
T=2*pi*sqrt(1/4)
T=2*pi*1/2
T=pi
