3.
A portion of an embankment having a uniform up-gradient 1 in 500 is circular with radius 1000 m of the centre line. It subtends 180° at the centre. If the height of the bank is 1 m at the lower end, and side slopes 2:1, the earth work involved.

Since height from the downside is h1 = 1m.
Consider hm = 2,
h2 = 3.
Then proceed with the Simpson's rule = (L/6)(A1 + 4AM + A2).
L = π x R.
L = 3140.
A1 = S.h1^2 = 2(given).1(height from downside) = 2.
A2 = S.h2^2 = 2 * 9 = 18.
AM = S.hm^2 = 2 * 4 = 8.
Inserting in the Simpson;
(3140/6)(2 + (4*8) + 18).
=27213.333.
Approximately 27,500 m^3.

Assume semi-circle plan, embankment section of a triangle with 1 m ht and 1 m base, so the total length of the embankment is π* 1000m, so final section with triangle ht 6.283 m.
Then solve, you will get the answer.
Then solve, you will get the answer.
