Question

What angle does a radius subtend at the centre of a circle?

• A. $0^{\circ }$
• B. ${180}^{\circ }$
• C. ${360}^{\circ }$
• D. None of these

Answer 1

The correct option is D

None of these

Radius is not a chord of the circle, i.e., its end points do not lie on the circle. It starts from the centre and ends at the circle. So, it does not subtend any angle at the centre.
