A semicircular metal ring subtends an angles of `180^(0)` at the centre of the circle. When it is heated, this angle

In a circle with centre O an are ABC subtends an angle of 140^(@) at the centre of the circle . The chord AB is produced to point P. Then angleCBP is equal to :

In a circle with centre O. an arc ABC subtends an angle of 136^(@) at the centre of the circle. The chord AB is produced to a point P. Then angle CBP is equal to :

If chord AB subtends an angle 50^(@) at the centre of a circle then the angle between the tangents at A and B is

A chord of length 10 cm subtends an angle of 120^(@) at the centre of the circle. Find the distance of the chord from the centre.

If a chord AB subtends and angle of 60^(@) at the centre of a circle, then the angle between the tangents to the circle drawn from A and B is

If a chord AB subtends and angle of 60^(@) at the centre of a circle, then the angle between the tangents to the circle drawn from A and B is

Let p and q be the length of two chords of a circle which subtend angles 36^@ and 60^@ respectively at the centre of the circle . Then , the angle (in radian) subtended by the chord of length p + q at the centre of the circle is (use pi=3.1 )

O is the centre of the circle and arc ABC subtends an angle of 130^@ at the centre. If AB is extended to P, find anglePBC

Equal chords of a circle subtend equal angles at the centre.

Equal chords of a circle subtend equal angles at the centre.
