The correct answer is 21π/5

Explanation:
The arc length of a circle is given as = radius × angle subtended by the arc at centre.
Here, r = 7 cm.
θ = 3π/5
Therefore, arc length, l = rθ = 7×3π/5 = 21π/5

What is the arc length when θ = 3 pi over 5 and the radius is 7 cm? (5 points) 3 pi over 35 cm 12 pi over 5 cm 6 pi over 5 cm 21 pi over 5 cm
