• 3cm

• 3.5cm

Answer 1

A pair of tangents can be constructed from a point P to a circle of radius 3.5cm situated at a distance of 5cm from the centre.

Explanation:-

The pair of tangents can be drawn from an external point only, so its distance from the centre must be greater than radius. Since only 5cm is greater than radius of 3.5cm. So the tangents can be drawn from the point situated at a distance of 5cm from the centre.
