Question

Find the value of arc s

Answer 1

Answer:

≈ 38.64 units

Step-by-step 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 × $\frac{246}{360}$

        = 2π × 9 × $\frac{41}{60}$

        = 18π × $\frac{41}{60}$

        ≈ 38.64 ( to 2 dec. places )
