Question

In a unit​ circle, the radian measure of the central angle is equal to the length of the ________. A:Raduis B:intercepted arc C:Circumfrence D:Diameter

Answer 1

B:intercepted arc

Explanation:

Recall from the knowledge of geometry:

That arc (s) = θ * r(1)

Here;

θ is known as the central angle which is measured in radians

r is the radius of the dimensionless

Hence, suppose the unit circle have a radius of 1 m length. Then, it is pertinent to understand that the arc will also varies directly proportional to the central angle.
