What distance does an object travel in one lap around a circle?

Let say the circle is of radius R

then one lap is means the total distance the total length of the circle

here the length of circle is same as circumference

so it is given as

So here the length of lap is given as length of circle which is given as above

An object taking one lap around the circle will be covering a distance equal to the circumference of the circle.

Explanation

1 lap around a circle means one complete rotation of a track which is circular. So the distance covered in covering one complete circle will be equal to the circle circumference.

Let us consider, R as the circle radius, then the distance covered by an object for a single lap will be equal to the circle circumference which is equal to 2πR.
