# A well with 10 m inside diameter is dug 14 m deep. Earth taken out of it is spread all around to a width of 5 m to form an embankment. Find the height of the embankment.

Answer :

Volume of a cylinder =

Radius of well = 5m , Height of well = 14m

Volume of the well =

For embankment, radius = 5+5 =10 m and let height be h m

Volume of well = Volume of embankment

⇒ h = 4.67 m
