The distance between two parallel tangents to a circle of radius $6 \mathrm{cm}$ is $14 \mathrm{cm}$.

$$If a chord $PQ$ subtends an angle of $70°$ at the centre of a circle, then angle between the tangents at $P$ and $Q$ is also $70°$.  

Length of tangent from an external point $P$ on a circle $C(O,r)$ is_____than $OP$. (greater/lesser)

The distance between two parallel tangents to a circle of radius $6 \mathrm{cm}$ is_____

If the angle between two tangents drawn from a point $P$ to a circle of radius $r$ and centre $O$ is $60°$, then $OP=$_____ $\times r$

In the fig., two concentric circles with centre $\mathrm{O}$ are shown. AB and APQ are tangents to the inner circle from point $\mathrm{A}$ lying on the outer circle. If $\mathrm{AB}=7.5 \mathrm{cm}$, then $\mathrm{AQ}$ is equal to:

In the figure, two circles with centres $A$ and $B$ touch each other externally at point $R$. The length of $PQ$(in $\mathrm{cm}$) is:

Quadrilateral $ABCD$ circumscribes a circle as shown in fig. The side of quadrilateral which is equal to $AP+BR$ is:
