You can put this solution on YOUR website! find the arc of a circle of radius 81cm intercepted by the central angle of a=2radians???
-----
Comment: Radian measure is a count of times the radius can be laid
on an arc of a circle.
----
Formula: theta = (arc length)/(radius)
Your Problem:
2 = (arc length)/81
---
arc length = 2*81 = 162 cm
