Question

Two concentric circles with centre o have a b c d and points intersection with line l preferred is equal to 12 cm bc is equal to 8 cm find the length of abcd ac and bd

Answer 1

Answer:AC=BD=2cm

Step-by-step explanation:now since in the circle OZ perpendicularly bisects BC and AD(. BECUSE it is distance form the circle bisexts the chord)

Hence- ZC=ZB=1/2 OF 8 = 4 CM. - i

AZ=DZ= 1/2 OF 12 = 6cm. - ii

NOW subtracting ii from i

= AZ-CZ=DZ-VS=(6-4)cm

=AC=BD=2cm

Hence = AC=BD= 2cm
