Question

Which of the given line segments is a radius of the given circle if O is the center of the circle?

• A. PQ
• B. OA
• C. MN

Answer 1

The correct option is B OA

The line segment joining the centre of the circle to any point on the circle is called the radius of the circle. In this case, the line segments OA, OP and OQ join the centre of the circle (O) to a point on the boundary (A, P and Q). Thus, OA, OP or OQ are the radii.
