`A P` and `P Q` are tangents drawn from a point `A` to a circle with centre `O` and radius 9cm. If `O A=15 c m ,` then `A P+A Q=` (a) 12cm (b) 18cm (c) 24cm (d) 36cm

A P and A Q are tangents drawn from a point A to a circle with centre O and radius 9cm. If O A=15 c m , then A P+A Q= (a) 12cm (b) 18cm (c) 24cm (d) 36cm

AP and AQ are tangent drawn from a ponit A to a circle with centre O and radius 9cm. If OA = 15 cm. then AP + AQ = …….. Cm.

In Fig. 10.87, two equal circles touch each other at T , if Q P=4. 5 c m , then Q R= (FIGURE) (a) 9cm (b) 18cm (c) 15cm (d) 13.5cm

In Figure, two equal circles touch each other at T , if Q P=4. 5 c m , then Q R= (a) 9cm (b) 18cm (c) 15cm (d) 13.5cm

P is a point in the plane of a circle with centre O and radius 4 cm. If OP = 3 cm, ..... tangent/s can be drawn to the circle from point P.

In Figure, there are two concentric circles with centre O . P R and P Q S are tangents to the inner circle from point plying on the outer circle. If P R=7. 5 c m , then P S is equal to (a) 10cm (b) 12cm (c) 15cm (d) 18cm
