\[\text{S.}\]
\[Решение.\]
\[В\ треугольнике\ AOB:\]
\[AO = OB = R;\]
\[\angle AOB = 120{^\circ};\]
\[AB = 2\sqrt{3};\]
\[h - высота.\]
\[BM = \frac{1}{2}AB:\]
\[tg60{^\circ} = \frac{\text{BM}}{d} = \sqrt{3};\]
\[BM = \sqrt{3}d;\]
\[2BM = 2\sqrt{3}d;\]
\[S = 2\sqrt{3}d \cdot h.\]
\[Ответ:2\sqrt{3}\text{dh.}\]
