A well of diameter 3 m is dug 14 m deep. The earth taken out of it has been spread evenly all around it in the shape of a circular ring of width 4 m to form an embankment. Find the height of the embankment.

**Solution:**

Diameter of well **m**

Radius of well **m **

Height of well **m**

**Volume of earth dug out =Volume of well**

Let height of embankment **m**

**Volume of embankment**

**According to given condition we have:**

**Volume of Earth Dug out= Volume of embankment**

**m**
