Let `C` be the mid-point of an arc `A B` of a circle such that `m\ hat A B=183^0dot` If the region bounded by the arc `A C B` and line segment `A B` is denoted by `S ,` then the centre `O` of the circle lies in the interior of `S` (b) in the exterior of `S` on the segment `A B` (d) on `A B` and bisects `A B`

Explanation

Given ,`hat A B=183^0dot`
with given information , the corresponding figure would be look like in picture.
Centre will lie inside the shaded region of `S(arc AB)`.
