Why is 2.01 the accepted value for a pendulum?

[LadiesMan]

1. Why is 2.01 the accepted value for a pendulum?



2. T = 2pi(L/G)^1/2
L is the length of the Pendulum
G is the Gravitational Force



3. This is what the teacher did but I'm not sure why it works this way:

T = 2pi(L/G)^1/2
T= (2pi/(G)^1/2) x (L)^1/2
T = 2pi/(9.8)^1/2
T = 2.01

What happened to the Length?

Thanks for your help! =)

That is for a pendulum of length 1m,

That's the period of a simple pendulum having a length of 1 m.
