The correct answer is $\\boxed{\\text{A}}$.<\/p>\n

The angle subtended by the surface of sewer water with partial flow, at sewer centre is 120\u00c2\u00b0. This means that the sewer is 120\u00c2\u00b0 wide at the surface. If we assume that the sewer is a perfect circle, then the depth of the sewer is half of the width, or 20 cm.<\/p>\n

Option B is incorrect because it is the depth of the sewer if it were a perfect square. Option C is incorrect because it is the depth of the sewer if it were a perfect triangle. Option D is incorrect because it is the depth of the sewer if it were a perfect rectangle.<\/p>\n","protected":false},"excerpt":{"rendered":"
