Which of the following can be the angle subtended by a minor arc at the centre?

The angle subtended by a minor arc in its alternate segment is…………….

Theorem 2: The no.of Radians in an angle subtended by an arc of a circle at the centre = arc/radius

The length of a minor arc is 2/9 of the circumference of the circle. Write the measure of the angle (in degrees) subtended by the arc at the centre of the circle.

Keeping current per unit length of arc constant, the variation of magnetic field at the centre of an arc (B) with the angle subtended by the arc at the centre (theta) can be best represented by

Keeping current per unit length of arc constant, the variation of magnetic field at the centre of an arc (B) with the angle subtended by the arc at the centre (theta) can be best represented by

The length of an arc of a circle of radius 25 cm is 32 cm. Find the angle subtended by the arc at the centre of the circle.

If the chord of a circle is equal to the radius of the circle, then the angle subtended by the chord at a point on the minor arc is .........
