In any event, you might relate for the students the circumference of
the circle to the more general "perimeter" of a closed figure.

In particular, the circumference (perimeter) is a linear measure. This
means if you "cut" the curve and formed a straight line segment out of it,
the length of that segment is the circumference of the circle.

Not being picky, and in fact in agreement, but it has an "equivalent",
or "corresponding" linear measure, which we find satisfactory and
useful. E.G. the distance along a level surface travelled in one
revolution of the wheel. But then again, that's how we measure any
distance; a comparison with some arbitrary linear measure [tape or
stick.]
