The angle subtended at the center of a circle of radius 15 cm by an arc of length 15.7 cm is (pi = 3. 14 )

If d is the distance from a point P to the center of the circle of radius r and d-r gt0 , then the point P lies………… the circle. (outside/inside/on)

Let PQ and RS be two parallel chords of a given circle of radius 6 cm, lying on the same side of the center. If the chords subtends angles of 72^(@) and 144^(@) at the center and the distance between the chords is d, then d^(2) is equal to
