I need to know the value of s and a. S is the side length of the hexagon and a is the smallest width.

The only value I know is A = 48” (inches) and the circumradius which is also 48”.

I need to know the value of $s$ and $a$.
$S$ is the side length of the hexagon and $a$ is the smallest width.

The only value I know is $A$ = 48 inches, and the circumradius which is also 48 inches.

Could you provide the original wording of the problem?
As given, it's both sloppy and incorrect.

Is it a regular hexagon? .It should say so ... clearly.

There seems to be four variables: $S,\,s,\,A,\,a.$

If the smallest width is 48, the circumradius is not 48.

Are you also known as "september.cooper"?
It doesn't matter.
