Area = π * r2 = π * 142 = 196π in2
The area is 1583 square units, approx.
A regular nonagon with a side length of 9 has an apothem of 12.4 not 16. So the question is inconsistent.

Area of a nonagon with a circumradius of 2 units is 11.57 square units.
It is a plane area in the shape of a nonagon!
It is 72.3 square units, approx.
Area = π * r2 = π * 142 = 196π in2
The area is indeterminate, since the shape can be a long thin nonagon with minimum area or a regular one with maximum area.
The area of a regular pentagon with a radius of 7 is 10.1716. If the radius was 5, the area would be 7.26543.
