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

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, $$D = r\theta$$

the arc length formula is $l = r \times \theta$ l = arc length, substitute your information and claculate
