Question

In the diagram below, Θ is measured in radians. Which equation represents the relationship between the radius, r, and arc length, s?
Circle O is shown. Line segments A O and B O are radii with length r. Angle A O B has a measure of theta. Arc A B has a measure of s.

Answer 1

Answer:

$s = r \theta$

Step-by-step explanation:

There is a relationship between the central angle of a sector and the length of the arc enclosed by the two radii of the sector.

When the central angle of the sector

$\theta$

is measured in radian.

Then the relation between this angle and and the radius r, and the arc length , s is

$s = r \theta$

Answer 2

Answer:

s = Θ · r
