Answer:

pi  or approximately 3.14

Step-by-step explanation:

arc length = circumference * x/360  where x is the angle in degrees

Circumference = 2 * pi *r

arc length = 2*pi*r * x/360

We know r = 3 and x = 60

arc length = 2*pi*3 * 60/360

arc length = 6 pi *(1/6)

arc length =  pi

Using 3.14 as an approximation for pi

arc length = 3.14

Answer:

[tex]\pi[/tex]

Step-by-step explanation:

0/360 = s/c

60/360 = s/6pi

1/6 = s/6pi

1/6 * 6pi = s

pi = s

Therefore Pi or [tex]\pi[/tex] is the answer
