Answer:

8 inches

Explanation:

The circumference of a circular ring of the steel wire = 25.12 cm

To find the diameter of the circular ring, we will first find the radius of the circular ring, using the circumference, and then multiply it by 2.

We know that:

Circumference =
$2\pi r$

25.12 = 2 x 3.14 x r

r = 25.12 / (2 x 3.14)

r = 4 inches

Therefore, the diameter of the circular ring will be 2 x 4 = 8 inches.
