In general, in the case of a regular polygon, the apothem is the perpendicular distance from the center to a side of the polygon, while the radius is the distance from the center to a vertex.

Therefore, in our case,


\begin{gathered} apothem=a=OP \\ radius=r=OB,r=OA \end{gathered}

Notice that two radii are drawn in the figure.

As for the perimeter of the 8-sided polygon,


P=8(AB)

Thus, the answer is option D.
