Did you even consider if your answer makes any sense ??
6412 million is 6.4 billion.
Do you really think that the earth's population increased at a rate of 6.4 billion per year if the entire population is 6.3 billion??
According to your formula
dP/dt = .011(6.342)e^.011t
so when t=1 (from 2004 to 2005)
dP/dt = 70.53 million/year
6412 million is 6.4 billion.
