A. 10.6 m

B. 10.8 m

C. 10.9 m

D. 11.0 m

E. 11.2 m

F. 11.3 m

G. 11.5 m

H. 11.7 m

what is it?

assuming that by "radian" you mean "radius" and by "length of circle" you mean "length of arc", then you can figure out the circumference of the circle

12(radius) x 2 x pi = 24 pi = C

54 is .15 of 360, so taking .15 of 24 pi would be 3.6 pi.

if you need exact(rounded to tenths, just multiply by pi and round, you get 11.3 cm)

hope this helped

ah.. sorry, it's F.

(forgot to specify which answer, though i'm sure you're smart enough to figure that out on your own)
