Question

Which of the following segments is a radius of circle O?

Answer 1

I think it's RO if it's circle O

Answer 2

Answer: B.  $\overline{RO}$

Step-by-step explanation:

We know that the radius of a circle is a line segment which starts from the center of the circle and ends to any point on the circle.

From the given figure , it can be seen that there are three line segments in the circle which starts from center to a point on circle .

Thus, The radius of the circle with center O= $\overline{AO},\ \overline{RO},\ \overline{SO}$

From the given options , line segment $\overline{RO}$ is  a radius of circle O.
