A circle of radius 3 cm can be drawn through two points A, B such that AB=6 cm.

A tangent AB, at a point A of a circle of radius 5 cm, meets a line through the centre O at point B such that OB =12 cm. Length AB is

In a circle of radius 5 cm, AB and AC are two chords, such that AB = AC = 6 cm. Find the length of the chord BC.

Two circles of radius 1 cm touch at point P. A third circle is drawn through the points A, B and C such that PA is the diameter of the first circle and BC perpendicular to AP is the diameter of the second circle. The radius of the third circle in cm.

Draw a circle of radius 2.6 cm and mark a point p on it . Draw a circle of radius 1.3 cm passing through the point P and touching the circle only at P .

In a circle of radius 5cm, AB and AC are two chords such that AB=AC=6cm* Find the length of the chord BC

Two points A and B are 16 cm apart. A circle with radius 17 cm is drawn to pass through these points. Find the distance of AB from the centre of the circle.

Draw a circle with centre A and radius 3.5cm. Take a point B such that d(A,B)=8cm. Draw tangents to the circle passing through point B.

If AB =112cm, BC=16 cm and AB is perpendicular to BC, then the radius of the circle passing through the points A, B and C is
