Question

What is the arc length if Θ = 6 pi over 5 and the radius is 2 cm?

Answer 1

Arc length = 7.53 cm

Explanation:

We have given that : Radius = 2 cm

Angle =
`\theta= (6\pi)/(5)`

To find : Arc length(A)

Solution: The formula of arc length is

Arc length(A) = radius × angle(in radian)

`A= 2*(6\pi )/(5)`

A= 37.699/5=7.53 cm

Answer 2

The arc length :
L = r π (theta) / π = r *(theta) = 2 · 6 π / 5 = 12π / 5
( 12 · 3.14 ) : 5 = 7.536
Answer: 7.536 cm.
