Let A₀A₁A₂A₃A₄A₅ be a regular hexagon inscribed in a circle of unit radius. Then the product of the lenghts of the line segments A₀,A₁,A₂ & A₀A₄ is

A) 3/4 B) 3root 3 C) 3 D) 3root 3/2

line segments A0,A1,A2& …

Please check the question and repost it so that I may be able to help you. It is not clear as to which line segment is being talked about...

The information I could gather from the question were this being a regular hexagon inscribed in a unit circle, each side will be equal to the radius of the circle i.e. 1 unit

If this helps, then all the best, otherwise repost the question.
