# A well of diameter 3m, is dug 14m deep The earth taken out of it has been evenly spread all around it to a width of 4m, to form an embankment Find the height of the embankment use pi=22/7

The shape of the well will be cylindrical.

Depth (h 1) of well = 14 m

Radius (r 1) of the circular end of well =

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 2) as and inner radius (r 1) as.

Let the height of embankment be h 2.

Volume of soil dug from well = Volume of earth used to form embankment

Therefore, the height of the embankment will be 1.125 m.

The shape of the well will be cylindrical.

Depth (h1) of well = 14 m

Radius (r1) of the circular end of well =

Width of embankment = 4 m

From the figure, it can be observed that our embankment will be in a cylindrical shape having outer radius (r2) as and inner radius (r1) as.

Let the height of embankment be h2.

Volume of soil dug from well = Volume of earth used to form embankment

Therefore, the height of the embankment will be 1.125 m.

Radius of well , r = 3/2m

Height , h = 14m

Therefore, Volume of the earth taken out of the well
