Question

Jason found a steel wire in a form of a circular ring that had a circumference 25.12 inches. What would be the diameter of the wire?

8 inches
4 inches
7.85 inches
12.5 inches

Answer 1

the diameter would be twelve point five inches.

Answer 2

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.
