Question

Use the arc length formula and the given information to find θ.
s = 7 m, r = 12 m; θ = ?

Answer 1

Θ = 0.5833 radians = 33.4°

Explanation:

The arc length formula

⇒ s = r Θ

Where r is the radius , Θ is the angle in radians

So, Θ = s/r

If s = 7 m, r = 12 m

∴ Θ = 7/12 = 0.5833 radians = (7/12) * (180/π) = 33.4°
