Final answer:
The diameter of an egg batter pancake cannot be determined with the given information.

The question is asking for the diameter of an egg batter pancake in inches. To determine the diameter, we need to consider the size of the pancake and the amount of batter used. However, the given information does not provide the specific measurements of the pancake or the batter. Therefore, it is not possible to determine the exact diameter of the pancake without additional information.
