Question

In a village a well with 10 m inside diameter is dug 14m deep

Answer 1

Answer:

Given radius of the well = 5m

Height of the well = 14 m

Width of the embankment = 5 m

Therefore radius of the embankment = 5 + 5 = 10 m

Let h be the height of the embankment

Hence the volume of the embankment = volume of the well  

That is π(R – r)2h = πr2h

(102 – 52) x h = 52 x 14

(100 – 25) x h = 25 x 14

h = (25 x 14)/75 = 14/3

Therefore, h = 4.67 cm (nearly)
