Answer 1

The length of arc is (7/12)π cm.

Explanation:

Given that the formula to find the length of arc is Arc = (θ/360)×2×π×r where θ represents degrees and r representa radius. Then you have to substitute the following values into the formula :

`arc = (θ)/(360) * 2 * \pi * r`

`let \: θ = 30 \\ let \: r = 3.5`

`arc = (30)/(360) * 2 * \pi * 3.5`

`arc = (1)/(12) * 7 * \pi`

`arc = (7)/(12) \pi \: \: cm`
