The length of common chord of two intersecting circles is 30 cm. If the diameters of these two circles be 50 cm and 34 cm, calculate the distance between their centres.

The length of two parallel chords of a circle are 6 cm and 8 cm . The radius of the circle is 5 cm. Find the distance btween them if : (i) chords are on the same side of the centre. (ii) chords are on the opposite side of the centre.

A chord 16 cm long is 6 cm distant form the centre of the circle . Find the diameter of the circle.

The radius of a circle is 13 cm and the length of one of its chords is 10 cm. Find the distance of the chord from the centre.

Find the length of a chord which is at a distance of 4 cm from the centre of the circle of radius 6 cm.

Two circles have an external tangent with length 36 cm. The shortest distance between these circles is 14 cm. If the radius of the longer circle is 4 times the radius of the smaller circle then the radius of the larger circle in cms is

AB and CD are two parallel chords of a circle on opposite sides of a diameter such that AB = 24 cm and CD = 10 cm. If the radius of the circle is 13 cm, find the distance between the two chords.

The lengths of two parallel chords of a circle are 6 cm and 8 cm. If the smaller chord is at distance 4 cm from the centre, what is the distance of the other chord from the centre?

The lengths of two parallel chords of a circle are 6 cm and 8 cm. If the smaller chord is at a distance of 4 cm from the centre, what is the distance of the other chord from the centre?

The radius of a circle is 13 cm and the length of one of its chords is 24 cm. Find the distance of the chord from the centres.

A chord of length 6 cm is drawn in a circle of radius 5 cm. Calculate its distance from the centre of the circle.
