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.**
