A pair of tangents can be drawn from a point $\mathrm{P}$ to a circle with a radius of $3.5 \mathrm{cm}$ located at a distance of ____ from the centre.

A line that intersects a circle at two points.

Any tangent on a circle can be drawn only if the distance from the point to be drawn is equal to or greater than the radius of the circle.

The radius of the circle is $3.5cm$ from the centre, which is inside the circle.

As a result, no tangent can be drawn if the point is inside the circle.
