Question

Find the value of arc s

Answer 1

≈ 38.64 units

Explanation:

The length of arc s is calculated as

circumference of circle × fraction of circle

The central angle subtended by arc s is 360° - 114° = 246° then

arc s = 2πr ×
`(246)/(360)`

= 2π × 9 ×
`(41)/(60)`

= 18π ×
`(41)/(60)`

≈ 38.64 ( to 2 dec. places )
