By definition, the circumference of a circle is given by:

$C = 2 \pi r$

Where,

r: radius of the circle.

We have then, that the radius of the outer circle is given by:

r = 15 + 3

r = 18

Then, replacing values we have:

C = 2 (3.14) (18)

C = 113

Answer:

The circumference of the outer edge of the frame is:

113 inches
