AD is the diameter hence OD will be radius.
The hexagon is regular so all sides will be equal.
Triangle OBC will form an equilateral triangle.
OB = OC = BC = radius
Qt A
Radius OD = BC = EF = side of hexagon
Qt B
The length of arc \(\widehat{FE}\)
This can be calculated as = \(\frac{angle EOF}{360} * 2 * pi * radius\)
= \(\frac{60}{360} * 2 * pi * EF\)
= \(\frac{pi}{3} * EF\)
= 1.046 * EF
So Qt B > Qt A

We are told that hexagonal is inscribed inside the circle, the basic property of hexagonal states its consists 6 equilateral triangle.
Hence all side of the given triangle are equal.
But,
radius OD is straight line segment and FE is curve path,
Hence, FE is greater.
