In a circle of radius r, a chord subtends an angle $\theta$ (in radians) at the center. Which expression represents the length of the minor arc?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. r $\theta$

The length of the minor arc is given by:

s=r $\theta$

Therefore, the required expression is:

Arc length = r $\theta$
