no dear...it is because u will get the area of shaded region only when u will subtract the area of the sector from the area of the whole quadrilateral...that's why I have subtracted 13.09 from 43.25
Area of sector is 13.09? Isn't it the area of some triangle
There theta is 120 for the sector
I m not getting what u wanna say..???
but theta is 30 and it's double is 60..that's why I have taken 60°..
may be I did some mistake I'll see once more
It's not sin theta yaar it's cos theta so theta is 60 and its doubled and its 120
ya I got it..
Please help for my other question
I will try..
