Given a well with diameter 3 m and height 14 m. The earth dug out from well is used to make a circular embankment of 4m width.
We have to find the height of the embankment.
Let R be the radius of well
Let H be the height of well
Let r be the radius of embankment
Let h be the height of embankment
Width of the circular embankment
According to the question
Volume of the earth dug = Volume of the circular embankment
