use the arc length formula and the given information to find the indicated quantity?

r= 16 in., thetha=8 rad; find s

Verified Answer :

Arc length formula =
S= (theta)r
r=16
theta=8 rad (radians are just a ratio rather than a measurement so you can just say that theta = 8)
16
8=128
So, S is equal to 128 inches.
