The period t ( in seconds) of a simple pendulum as a function of its length l(in feet) is given by t(l) = xpie sqrt 1/32.2

a. Express the length l as a function of the period t

b. How long is a pendulum whose period is 3 seconds.

Is the answer 2 sec for a and 2.25 feet for b?????

the length of a simple pendulum varies directly with the square of its period. if a pendulum of length 2.25 meters has a period of 3 seconds, how long is a pendulum of 8 seconds?
