JEE Advanced Mathematics question
Not in JEE syllabus
The angle of elevation of the top of a vertical pole when observed from each vertex of a regular hexagon is . If the area of the circle circumscribing the hexagon be metre then the area of the hexagon is
Answer: (D)
Solution
Equal elevations from all vertices put the foot of the pole at the centre of the hexagon, at distance (circumradius) from each vertex. (The pole's height only fixes ; it is not needed for the ratio.)
