Question

Find the length of each arc. Round your answer to the nearest tenth

Answer 1

D

Explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr ×
`((\pi )/(6) )/(2\pi )` ( cancel the 2π )

= 12 ×
`(\pi )/(6)` = 2π ≈ 6.3 ( to the nearest tenth ) → D
