If two parallel chords of a circle,having diameter 4 units,lie on the opposite sides of the centreand subtend angles cos^(-1)((1)/(7)) and sec^(-1)(7) at the centre respectively,then the distance betweenthese chords,is: (a) (4)/(sqrt(7)) (b) (8)/(sqrt(7)) (c) (8)/(7) (d) (16)/(7)

If two parallel chords of a circle, having diameter 4 units, lie on the opposite sides of the centreand subtend angles cos^-1(1/7) and sec^-1(7) at the centre respectively, then the distance betweenthese chords, is: (a) 4/sqrt7 (b) 8/sqrt7 (c) 8/7 (d) 16/7

Two parallel chords of a circle, of diameter 20 cm lying on the opposite sides of the centre are of lengths 12 cm and 16 cm . The distance between the chords is

AB and CD are two parallel chords of a circle of radius 6 cm lying on the same side of the centre. If the chords subtend angles of 72^circ and 144^circ at the centre, find the distance between the chords.

Two parallel chords of a circle,which are on the same side of centre,subtend angles of 72^(@) and 144^(@) respetively at the centre Prove that the perpendicular distance between the chords is half the radius of the circle.

The chord of a circle is equal to its radius, find the angle subtended by this chord at the centre.
