s = 8 and a = 1.3 are not compatible for a regular hexagon.
4.5
The answer depends on what the lengths s and a are meant to represent.
The perimeter of a hexagon is the sum of its 6 sides.
If the circumference of the circle is 2.5 inches then its diameter is 2.5/pi = 0.796 of an inch rounded up to 3 decimal places
A decimal is a number, while an inch is a unit of length. The two are not directly related, and this question cannot be answered as such. If the decimal number were inches, however, it would be sufficient to round to the nearest integer. If, for instance, they were feet, it would be best to multiply by 12, round to the nearest integer, and then divide by 12.
The area is 166.3 square inches.

It's regular, it has 6 sides and each side is 8.2 inches. Wrap a wet towel round your head and I'm sure you'll be able to work it out.
The question was extremely poorly worded since it gave no information on what S and a were. However, having figured that out, the answer is 166.3 square units.

It is 679 square metres.
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
A hexagon can be drawn either with a compass or round object, or free hand. A hexagon has six equal sides and six equal angles. For a perfect hexagon, a compass is recommended. * * * * * While a hexagon does have six sides and six vertices, these need not be equal. If the sides are all equal AND the angles are equal, then the hexagon is a regular hexagon.
The exterior angles of any polygon add up to 360° (imagine walking round any polygon - you will have made a complete turn). There are six external angles in a hexagon. If it is a regular hexagon, each external angle will be 360°/6 = 60°.
