Question

Can someone answer my question please

Answer 1

≈ 1.5 radians

Explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

Here arc = 16 , then

2πr ×
`(0)/(2\pi )` = 16 ← cancel the 2π on numerator/denominator

11 ×θ = 16 ( divide both sides by 11 )

θ ≈ 1.5 radians ( to the nearest tenth )

Answer 2

Explanation:

Arc length=∅/360×2πr (can't find the symbol of theta, use ∅ instead LOL)

`(\theta )/(360)\cdot 2\pi \left(11\right)=16`

`(\theta )/(360)=(16)/(22\pi )`

`\theta \:=(16)/(22\pi \:)\cdot 360`

`{\theta}=83.34`
