Question

What is the arc length if Θ = 2 pi over 7 and the radius is 3 cm? Please explain how to do it

Answer 1

the definition of the angle in radians is "the angle subtended at the centre of a circle by an arc equal in length to the radius"

so if the arc length is D,

\(D = r\theta\)

Answer 2

the arc length formula is

\[l = r \times \theta\]

l = arc length, substitute your information and claculate
