Concentric Circles Problems
Concentric Circles Problems
Concentric Circles: The circle which have common centre point and different radius are called concentric circles.
Illustration: Two concentric circles with centre O have, A, B, C, D as the points of intersection with the line l as shown in the diagram. If AD = 12 cm and BC = 8 cm, find the lengths of AB, CD, AC and BD.
SOLUTION Since Similarly, Now, Also, and, |  |
Illustration: Two concentric circles and
with centre O have, A, B, C, D as the points of intersection with the line l as shown in the diagram. If AD = 8 cm and BC = 6 cm, and the distance of the chord from centre is 2 cm,find the length of radius of two circles.
SOLUTION Since Similarly, Now
Now
Hence radius of circle
