Use the above $F{e}_{-}F{e}_{3}C$ equilibrium phase diagram to consider $6\mathrm{.}0$ kg of austenite containing $0\mathrm{.}45w+\%C$ cooled to $726C.$

$($a$)$ What is the proeutectoid phase? $(3$ Points$),$

$($b$)$ How many kilograms each of total ferrite and cementite form? $(6$ Points$)$

Can you answer these questions due to the graph asap pls
