Answer 1

The Tur OC 101 discusses how much of the sh'mone esre (amida) one needs to have concentration on while saying. Amid that, he writes:

The rabbi, Rabbi Eliezer, wrote that a person should accustom himself that he has concentration, at least, for the closure of each benediction. For they have, [all told,] one hundred thirteen words, just as there are [one hundred thirteen words] in the prayer of Chana and one hundred thirteen times "lev" [="heart"] in Chumash, to indicate that one needs to have concentration of the heart for them.

Answer 2

Chanoch lived for 300 years after he begat Mesushelach. Mesushelach was 187 when he begat Lemech. So, when Chanoch was "no longer", Lemech was...113!

Answer 3

113 is the number of the final daf in Sanhedrin.
