Answer 1

Answer:

The length of arc is (7/12)π cm.

Step-by-step 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 :

$arc = \frac{θ}{360} \times 2 \times \pi \times r$

$let \: θ = 30 \\ let \: r = 3.5$

$arc = \frac{30}{360} \times 2 \times \pi \times 3.5$

$arc = \frac{1}{12} \times 7 \times \pi$

$arc = \frac{7}{12} \pi \: \: cm$
