Find the length of the arc, s, on a circle of radius r intercepted by a central angle θ. Express arc length in terms of π. Then round your answer to two decimal places.
Radius, r = 12 feet; Central angle, θ = 275°
--------
Since radian measure of theta = (arc length/radius)
arc length = (measure)*(radius)
-----
275 degrees = (275)(pi/180) = 1.5278 radians
----
Ans: arc length = 1.5278*12 = 18 1/3 ft
