Question 392084
an arc of length 32 inches is found in a circle with a radius of 8 in. 
find the measure of the central angle which intercepts this arc.
----
The circumference is 2(pi)r = 16pi inches.
-------------------
Use a proportion to find the central angle.
angle/arc = angle/arc
-----
angle/32 = 360/(16pi)
---
angle = 32[360/(16pi)]
-----
angle = 229.18 degrees
