Answer:

The shape of the well will be cylindrical as shown in the figure below:

Given:

Depth (h

1

) of well = 14 m

Radius (r

1

) of the circular end of well =

2

3

m

Width of embankment = 4 m

From the figure, it can be observed that our embankment will be in a cylindrical shape having outer radius, (r

)=4+
