There is a mistake in your question here is my proof:
r=
(C)/(2 \pi)

1. r=
(6)/(2 \pi)
r≈0.95

2. r=
(12)/(2 \pi)
r≈1.91

3. r=
(24)/(2 \pi)
r≈3.82

4. r=
(48)/(2 \pi)
r≈7.64

We can get the circumference of any circle in terms of the radius with this formula. C = 2
\pir.

Where r is the radius of the circle.

And we will use 3.14 for
\pi.

Plug in all the values.

C = 2 * 3.14 * 2

C = 12.56

So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
