answer

2.9 radians

step-by-step explanation

find the circumference = 2r pi

r = 2

c = 2 * 2 * pi = 4 pi

find the ratio of arc length to circumference

arc / c = 5.8/4 pi

this is equal to the ratio of radian measure / 2pi (since there are 2pi radian in a full circle)

5.8/4 pi = radian measure / 2pi

radian meaure = 5.8 * 2 / 4 = 2.9 radians
