The radius of a circle is 8 cm and O is its centre. If `angle AOB=60^(@)` and AB is a chord, then what is the length of the chord AB?

The length of two chords AB and CD of a circle with its centre O are equal . If angle AOB 60^(@) and CD = 6cm then calculate the length of the radius of the circle .

If the radius of the circle above is x, angle AOB=120^@ , and O is the center of the circle, what is the length of chord AB, in terms of x?

The two chords AB and CD of a circle with centre at O are equal. If angle AOB = 60^(@) and CD =r cm , then find the radius of the circle.

The radius of a circle is 10 cm and the perpendicular form the centre to a chord is 8cm. Find the length of the chord. (ii) The radius of a circle is 10 cm. its one chord is 16 cm long. Find the perpendicular distance of this chord form the centre. (iii) in the adjoining figure O is the centre of circle. the radius of circle is 17 cm . if OC=8cm, then find the length of chord AB. (iv) In the adjoining figure, OMbotAB , radius OC=5cm and chord AB=8cm .Find the length of OM.

Length of two chords AB and CD of a circle with centre O are equal. If angleAOB = 60^@ and CD = 6cm then find the length of the radius of the circle.

PQ and AB are two equal chords of a circle with centre O, If anglePOQ= 60^@ and AB = 8.5 cm, then calculate the length of diameter of it.

In the given figure, O is the centre of a circle of radius 13 cm and AB is a chord perpendicular to OD. If CD = 8 cm, then what is the length (in cm) of AB?

O is the centre of the circle.P is an external point.If AP=8cm ,Ap=BP and angleAPB=60^(@) ,then find the length of the chord AB.
