O C=ar

Answer 1

None of these formulas can be used to find the circumference of a circle.

The circumference can be found by using the formula diameter x pi or the formula (radius x 2) x pi.

Hope this helps! :)

Answer 2

Answer and Step-by-step explanation:

The circumference of a circle is denoted by:
`C=2\pi r=\pi d`, where d is the diameter and r is the radius. Either equation can work because the diameter is simply twice the radius.

So, look for the answer choice that matches the above equation. (Note that the choices given are unclear, unless there's some other information given that's missing here)
