Step-by-step explanation:

See attachment for proper presentation of question.

From the attachment, we have:

Required

Determine the scale factor

To solve this, simply divide the circumference of A' by that of A.

This gives the scale factor used

i.e.

Substitute values for A and A'

Hence, the scale factor used is 1.5

Additional Note:

If the given parameters had been the area of A and A', you'll need to first solve for the radius of both circles.

Then determine the scale factor by A'/A

answer: it would most likely be y=6 and 5/7.
