We can get the circumference of any circle in terms of the radius with this formula. C = 2[tex] \pi [/tex]r.

Where r is the radius of the circle.

And we will use 3.14 for [tex] \pi [/tex].

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.

There is a mistake in your question here is my proof:
r=[tex] \frac{C}{2 \pi} [/tex]

1. r=[tex] \frac{6}{2 \pi} [/tex]
r≈0.95

2. r=[tex] \frac{12}{2 \pi} [/tex]
r≈1.91

3. r=[tex] \frac{24}{2 \pi} [/tex]
r≈3.82

4. r=[tex] \frac{48}{2 \pi}[/tex]
r≈7.64
