Answer:


4\pi

Explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation
x*(\pi )/(180), x = 72

S =
72*(\pi )/(180) * R

given that R = 10

S =
(72*10*\pi )/(180)

S =
(720*\pi )/(180)

We simplify 720 as 180 goes into 720 4 times and we get

S =
4\pi

Hope this helps
