A circle is a curve sketched out by a point moving in a plane. The circumference of the ring of fire is 6.2831 meters.
<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The circumference of the ring if the radius is 1 meter is,
Circumference of the ring = 2πr = 2 × π × 1 = 6.2831 meters
Hence, the circumference of the ring of fire is 6.2831 meters.

I don't quite understand the question but from what it's given us so far, I can only assume that it is asking which axis the both of them measured?
Vivian measured the X-Axis, as it said she measured it as 6 units long.
Brook only stated that the distance on the line is 4 units, so I can only assume that she measured the Y-Axis.
I don't know if this helped but if so please give brainliest :D
