Question

What is the arc length when Θ = 4 pi / 7 and the radius is 5 cm?

20 pi over 7cm

4 pi over 7cm

2 pi over 7cm

24 pi over 7cm

Answer 1

\(\bf \textit{arc length}=s=\theta\cdot r\)

Answer 2

r = radius of course

Answer 3

What does s stand for? @jdoe0001

Answer 4

s = arc length

Answer 5

\(\bf \textit{arc length}=s=\theta\cdot r\qquad r=5\qquad\theta=\cfrac{4\pi}{7}\qquad thus\qquad
s=\cfrac{4\pi}{7}\cdot 5\)
