At time 57:20, since when does the area of the top of a circular specimen not contain pi?

Sir how force along OA is having component of σ3 --( σ3 being perpendicular to OA ). As component of anything perpendicular to it is always 0. Same with OB and σ1. Do you want to say forces acting perpendicular to OA and OB would be σ3sinθ and σ1cosθ respectively?? @1:04:23
