vredina [299]3 years ago
3 0

Answer:

C

Step-by-step explanation:

There are two arcs a major and a minor arc. You should never have to rely on a diagram to get the right answer.

The circumference is 2 * pi * r

r = 6 km

C = 2* pi * 6

C = 12 pi

The arc size is

arc size = 135 / 360 * 12pi

arc size = 3/8 * 12 pi

arc size = 4 1/2 pi = 9 pi /2  km
