Final answer:
In a right-aligned cell with content exceeding its width, the content typically overflows and is visible if the adjacent cell is empty; otherwise, it is hidden.
Step-by-step explanation:
When a cell is right-aligned and the content's length is more than the cell width, the behavior of the content overflow depends on the program or application being used. However, typically in spreadsheet applications like Microsoft Excel, if the next adjacent cell to the right is empty, the content will be displayed as is, overflowing into the adjacent cell without altering the original cell's appearance. If the adjacent cell is not empty, the content that exceeds the width of the right-aligned cell will be hidden.
