The circumference of a circle is 2(pi)r. The wheel completes one rotation but only covers (pi)radians, should it not complete 2(pi) radians, therefore rotating out to 6.28? Alternatively, if only half of the circumference was unrolled, this image would be accurate. — Preceding unsigned comment added by RWW2 (talk • contribs) 21:08, 23 September 2021 (UTC)
