The length of time (T) in seconds it takes the pendulum of a clock to swing through one complete cycle is givenby the formula T=2pi square root of L divided by 32 where L is the length in feet, of the pendulum, and pi is approximately 22 divided by 7. How long must the pendulum be if one complete cycle takes 2 seconds?

T = 2(22/7)√(L/32) or T = 2(22/7)(√L)/32 ??? Whichever equation it is, insert 2 for T and solve for L.
