Question 1124490: Use the model for the period of a pendulum, T, such that T = 2π sqrt (L/ g),
where the length of the pendulum is L and the acceleration due to gravity is g.
If the acceleration due to gravity is 9.8 m/s2 and the period equals 5 s, find the length to the nearest cm
(100 cm = 1 m).

*For this, I am completely lost as to both how the equation should be set up and the steps needed to solve the problem. If someone could help, it would be greatly appreciated!*

.
T =   ====>  square both sides  ====>


 = 


 = L


L =  =  = 6.21 meters = 621 centimeters = 621 cm.
