Find the length of an arc of an 8" radius circle if the arc measures 45° 271 in.
871 in.
1671 in.

Step-by-step explanation:

The appropriate formula here is s = rФ, where Ф is the central angle in radians.  We are given r = 8" and Ф = π/4 radians.  Then the desired arc length is

s = (8")(π/4), or   s = 2π or approximately 6.28".  The three given possible answers are 'way off.

i think this could be a possible answer (1 / 84) -1

good luck! : d
