在扇形OAB中，∠AOB = 60°，点C是半径OA上一点，且OC = 6，将线段OC沿OB方向平移，当平移距离是6时，点C的对应点C’恰好落在弧AB上，求图中阴影部分的面积。---**Image Description:** * **Type:** Geometric figure. * **Main Elements:** * A sector of a circle is shown, with center labeled O and arc AB. * Line segments OA and OB are radii of the sector. * Point C is labeled on the line segment OA. * There is an arc from A to B. A point C' is labeled on the arc AB. * There is another point O' labeled near B. * A line segment O'C' is drawn, connecting O' to C'. * A line segment O'B is drawn, connecting O' to B. * There is a shaded triangular region O'BC'. * The point C is labeled on the line segment OA. * The point C' is labeled on the arc AB. **Extracted Text:** The image contains only a geometric figure and labels, but no text for a question stem, options, or other relevant information. Therefore, no text can be extracted.
