Quizplus · Accepted Answer

To find the internal dimensions, we need to subtract two times the wall thickness from the outside diameter. Therefore,
Internal diameter = outside diameter - 2 × wall thickness
Internal diameter = 1.925 in. - 2 × 0.047 in.
Internal diameter = 1.831 in.

Hence, the best choice is A).
