Seems the answer is correct for part 2 but is like I missed the process, for instance where you completed arc AB 6:38 to a circle with center M 7:11 . But initially that would make it a small circle with AM being radius (Rcos∅),am still seeing Rcos∅ with centre T, how is that?
I however do not understand how 20W and 100E can form a straight arc through the North Pole. Taking centre of the earth and AB, the arc AB does not pass through the North Pole. How do we explain this?
I use many, onenote, Microsoft whiteboard, xournal++ and stylus pen. There are many online whiteboards. I do connect a writing pad via USB on which I write on using stylus pen.
I really appreciate your work sir thanks a lot my God bless you.

From our syllabus we are using 180-(40+40)=100
100/360×2×22/7×6370
=11,122.22km
This ends up giving incorrect answer
I thought of the same thing
It doesn't give the right answer in some instances

What of when the two longitudes of A and B add upto 180 degrees?
sorry, I have used your method and it gives same answer as coursebook
Please,I want to know the app you use for the lecture.Heartly appreciate your kind response.Thanks
