. A well of diameter 3 m is dug 14 m deep. The earth taken out of it has been spread evenlyall


around it in the shape of a circular ring of width 4 m to form an embankment. Find the height of the embankment

 

Best Answer

Solution:The shape of the well will be cylindrical.

Depth (h1) of well = 14 m

Radius (r1) of the circular end of well = 3/2M

Width of embankment = 4 m

As per the question,

Our embankment will be in a cylindrical shape having outer radius (r2)as11/2 m and inner radius (r1) =3/2 m

Let the height of embankment be h2

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