Expert Answer:

Inner radius of the well = 10/2 = 5 m

Volume of the earth taken out = πR2L = (22/7)(5)(5)(14) = 1100 m3

Outer diameter of the embankment = 10 + 2x5 = 20 m

Outer radius of the embankment = 10 m

Volume of earth in embankment = π(Ro2 - Ri2)H

1100 = (22/7)(100 - 25)H

H = 14/3 m = 4.67 m
