Based on the area of the tabletop with the inner circle, the area after the inner circle has been cut out is 12,309 inch².
<h3>How do we find the new area of the tabletop?</h3>
We are told that the area of the tabletop is 12,463 inch². 
We then need to find the area of the circlular cutout as:
= π x radius x radius 
= 3.14 x 7 x 7
= 154 inch²
The new area after the cutout is removed is therefore:
= Current area - area of circular cutout 
= 12,463 - 154
= 12,309 inch ²
Rest of the question:
Area of table including the cutout is 12,463 square inches.
