Q2 of 59 Page 83

Line l touches a circle with centre Oat point P. If radius of the circle is 9 cm,answer the following.

(1) What is d(O, P) = ? Why ?


(2) If d(O, Q) = 8 cm, where does thepoint Q lie?


(3) If d(PQ) = 15 cm, How manylocations of point R are line online l ? At what distance will eachof them be from point P?



(1)The perpendicular distance of O from P = radius of the circle = 9 cm.

(2)Q lies in the interior of the circle because P lieing on the circumference of the circle is at a distance of 9 cm.


(3)Position of R is not specified.
