The centre of a circle is at O. AB and CD are two chordsof length `d and e` respectively. If P is the mid point of CD, then the length OP is:

In the adjoining figure, 'O' is the centre of the circle. OL and OM are perpendiculars from O to the chords AB and CD respectively. If OL=OM and AB=16 cm , then find the length of CD.

In the given figure, AB and CD are two equal chords of a circle, with centre O. If P is the mid-point of chord AB, Q is the mid-point of chord CD and anglePOQ = 150^(@) find angleAPQ

Given two concetric circles with centre O. A line cut the circle at A,B,C and D respectively. If AB=10cm, then find the length of CD.

In AB and CD are two equal chords of a circle with center O. OP and OQ are perpendiculars on chords AB and CD respectively. If anglePOQ=150^(@) then angleAPQ is equal to

In the given diagram 'O is the centre of the circle and AB is parallel to CD. AB = 24 cm and distance between he chord AB and CD is 17 cm. It the radius of the circle is 13 cm, find the length of the chord CD.

In the figure, O is the centre of the circle of radius 29 cm, OP bot AB, OQ bot CD and AB is parallel to CD. If AB = 40 cm and CD = 42 cm, then the length of PQ is: दी गयी आकृति में, O वृत्त का केंद्र है जिसकी त्रिज्या 29 सेमी है , OP bot AB, OQ bot CD और AB, CD के समान्तर है। यदि AB= 40 सेमी और CD = 42 सेमी है, तो PQ की लंबाई है

Two same circles of radius 5 cm has a direct tangent AB and a transversal CD which touch circle at A, B and C, D respectively. If CD = 24 cm then find the length of AB (in cm)?

In the figure given below, O is the centre of the circle. AB and CD are two chords of the circle. OM is perpendicular to AB and ON is perpendicular to CD. AB = 24 cm, OM = 5 cm, ON = 12 cm. Find the : (i) radius of the circle (ii) length of chord CD
