Question

the area of a sector of a circle of radius 15cm is 110cm², calculate the angle of subtended at yhe center of the circle by the arc?

Answer 1

Just visualise a V drawn from the ends of a chord to the centre. Similarly the angle subtended at the circles is the angle made by a chord to the circle. Just visualise a V drawn from ends of a chord to a point on the circle. ... The central angle will be <180° in a minor arc and >180° (reflex angle) in a major arc.
