The formula s=2pi√L/32 (pi as in 3.14) represents the swing of a pendulum, where s is the time, in seconds, to swing back and forth, and L is the length of the pendulum, in feet.
a) Rearrange and express the formula equal to the value of "l"
b) What is the length of a pendulum that makes one swing in 1.5 seconds? Round your answer to the nearest hundredth.
