A. 12.5 cm

B. 12 cm

C.

D. 24 cm

The lengths of two chords AB and CD of a circle with its centre O are equal. If ∠AOB = 60° and CD = 6 cm. then let us calculate the length of the radius of the circle.

P is any point in a circle with its centre O. If the length of the radius is 5 cm. and OP = 3 cm., then let us determine the least of the chord passing through the point P.

The two circles with their centres at P and Q intersect each other at the points A and B. Through the point A, a straight line parallel to PQ intersects the two circles at the points C and D respectively. If PQ = 5 cm., then let us determine the length of CD.

The two circles with centers X and Y intersect each other at the points A and B. A is joined with the mid-point ‘S’ of XY and the perpendicular on SA through the point A is drawn which intersects the two circles at the points P and Q. Let us prove that PA = AQ.

The length of each of two parallel chord is 16 cm. If the length of the radius of the circle is 10 cm, then the distance between two chords is

Ab and CD are two equal chords of a circle with its centre O. If the distance of the chord AB from the point O is 4 cm. Then the distance of the chord from the centre O of the circle is

The length of a radius of a circle is 13 cm. and the length of a chord of a circle is 10 cm, the distance of the chord from the centre of the circle is

The lengths of two chords of a circle with centre O are equal. If ∠AOB = 60°, then the value of ∠COD is

Let us fill in the blanks:

i. If the ratio of two chords PQ and RS of a circle with its centre O is 1 : 1, then ∠POQ: ∠ROS=_______________

ii. The perpendicular bisector of any chord of a circle is __________ of that circle.

Two equal circles of radius 10 cm. intersect each other and the length of their common chord is 12 cm. Let us determine the distance between the two centers of two circle
