QUESTION: 9

In the figure, AD is a straight line. OP is perpendicular to AD and O is the centre of both the circles. If AO = 34 cm, OB = 20 cm and OP = 16 cm, then the length of AD is

Solution:
QUESTION: 10

Two circles of radii10 cm and 8 cm intersect and the length of the common chord is 12 cm. The distance between their centers is

Solution:

Center of circles= O and O'
Radii = 10 and 8cm
common chord= PQ
OP= 10cm
O'P = 8cm
PQ= 12cm
PL= 1/2PQ
= 1/2 x 12
= 6cm
