what is the length of the indicated arc?
a) 2 pi
b) 4 pi
c) 9 pi
d) 18 pi
e) none of the above

B) 4 pi

Step-by-step explanation:

The arc is the circumference.

C = 2*pi*r

C = 2*pi *18

C = 36pi

A circle is 360 degrees.  The  are is covering 40 degrees

40/360 = 1/9

The arc is 1/9 of the circle, so it will be 1/9 of the circumference

1/9 C = 1/9 (36 pi)

arc = 4 pi
