An agriculture field is in the form of a rectangle of length 20m width 14m. A 10m deep well of diameter 7m is dug in a corner of the field and the earth taken out of the well is spread evenly over the remaining part of the field. Find the rise in its level.

Explanation

We have

Radius of the well =27​ m

Depth of the well =10 m

Volume of the earth dug =`pi(7/2​)^2 xx10m^3=358m^3`

Also we have

Length of the field=14m

breadth of the field =14m

Area of the field =`20 xx14m^2=280m^2`
