Question

A sixth part of a full circle i.e. a sextant subtends an angle of ........... at the centre.

• A. ${60}^o$
• B. ${90}^o$
• C. ${45}^o$
• D. None of these

Answer 1

The correct option is A ${60}^o$

When a circle is evenly divided into six sections by three perpendicular lines,

each of the six areas is a sextant.

Total angle subtended at centre of circle is ${360}^{\circ }$.

Angle subtended by sextant at the centre=$\frac{{360}^{\circ }}{6}={60}^{\circ }$

option A is the answer.
