Two chords AB and AC of a circle are perpendicular to each other. If AB =4 cm and AC =3 cm , then find the radius of the circle.

Two chords AB and AC of a circle are mutually perpendicular to each other. If AB = 4 cm and AC = 3 cm, find the length of the radius of the circle.

AB and AC are two such chords of the circle with centre at O that each is perpendicular..., r to the other. If AB=4 cm and AC=3 cm, then find the radiu of the circle.

In the given figure, the diameter CD of a circle with centre 0 is perpendicular to the chord AB. If AB = 8 cm and CM = 2 cm, find the radius of the circle.

Length of two chords AB and AC of a circle are respectively 8 cm and 6 cm and angle BAC = 90^@ . What is the radius of the circle?

AB and CD are parallel chords of a circle 3 cm apart. If AB = 4 cm, CD = 10 cm, then what is the radius of the circle ?

In the adjoining figure, O is the centre of the circle and AB is its diameter. If AC=8 cm and BC= 6cm, then find the radius of the circle.

In the adjoining figure, O is the centre of the circle and AB is its diameter. If AC=8 cm and BC= 6cm, then find the radius of the circle.

If in a triangle ABC, BE and CF are two medians perpendicular to each other and if AB=19 cm and AC=22 cm then the length of BC is

Chords AB and CD of a circle are parallel to each other and lie on opposite sides of the centre of the circle. If AB = 36 cm, CD = 48 cm and the distance between the chords is 42 cm, find the radius of the circle.
