The perpendicular from the centre to the chord bisects the chord. With radius 15 cm and distance 9 cm, half the chord is 12 cm. Therefore, the chord length is 24 cm.

The radius is half the diameter, so it is 13 cm. The perpendicular from the centre bisects the chord, giving half chord 12 cm. Hence, the distance is 5 cm.
The angle subtended by an arc at the centre is twice the angle subtended by the same arc at any point on the circle. Therefore, the required angle is 35°.
Yes. Other congruent triangles can be constructed on the same circumcircle. They have the same shape and size as the given triangle but are positioned differently on the circle.
No. There is no point that is equally distant from three collinear points. The perpendicular bisectors of AB and BC are parallel and never intersect. Therefore, no circle can pass through three collinear points.
