It is just like cylinder. First we have to find the volume of earth taken out which is:-
Diameter of well=14
Radius=14/2=7m
Height of well =12m
Volume of earth taken out =volume of the well dug
Volume of the well=pi *r square*h , whuch is
22/7*7*7*12
=1948m cube
Now the height of embankment =volume of earth taken out/pi*[(14)square - (7) square]
Which is 2m
