Respuesta :

circumference is 2r (pie).  so, the circumference would be 6 x pie.  6pie x 30/360.  so, the answer would be pie/2.

Hope this helps!  when i say pie, i mean 3.14
apologiabiology
find circumference
c=2pir
c=2pi3
c=6pi

so
360=whole circle
30/360=x/6pi
times 360pi both sides
30pi=60x
divide both sides by 60
(1/2)pi=x

the arc is (1/2)pi meters
