The question is...find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. Then it gives the radius r of 27 inches and an arc length s of 6 inches. How do I do that?

Reiny,
you should have come across the formula
arc length = r(theta), where theta is the central angle
6 = 27theta
theta = 6/27 radians
= 2/9 rad
