Determine the sine, cosine, and tangent of the angle.

C

Step-by-step explanation:

Arc length is given by Ф/360 ×2×r

where r =radius of circle =11 units

and Ф =97

Arc length = 97/360 ×2× × 11

18.63

The correct answer is option c.  18.6

Step-by-step explanation:

It is given that, Sector angle = 97° and radius = 11

To find the circumference

Circumference = 2πr   (where r is the radius of circle)

Here r = 11

Circumference  = 2 * 3.14 * 11 = 69.08

To find the arc length

Arc length = (97/360) * Circumference

= (97/360) * 69.08 = 18.61 ≈ 18.6

Therefore the correct answer is option c.  18.6
