Question

The lenght of the tangent from a point A to a circle, of radius 3 cm, is 4 cm.The distance (in cm) of A from the centre of circle is :​

Answer 1

Answer:

Let AT be the tangent drawn from a point A to a circle with centre

O and OA= 5 cm and AT= 5cm. Since tangent at a point is

perpendicular to the radius through the point of contact
