2. The radius of a circle with centre P is 25cm and the length the chord is 48cm find the distance of the chord from centre P of the circle.
3. If the length of the largest chord of a circle is 17cm find the radius of a circle.
4. The radius of a circle with centre O is 41 the length of the chord PQ of same circle is 80. Determine the distance of chord PQ from centre O.
5. In figure O is the centre of a circleAB=16cm , seg OM ⊥seg AB, seg ON⊥. seg CD If , OM=6cm then find seg ON. 6. HI and JK are two parallel chords of a circle which are on opposite side of the centre such that and the distance between them is 7cm then find the radius of the circle.
7. The radius of a circle is 16cm the mid point of chord of a circles lies on the diameter perpendicular to the chord and its distance from one end of the diameter is 3cm; find the ;length of that chord.
8. Find the area of triangle so formed in a circle of radius 40cm, if angle subtended by the chord at the centre of the circle is .
9. In a circle of radius 17cm two parallel chords of the length 30cm and 16cm respectively are drawn on the opposite of the centre then find the distance between them.
