Chord Theorem 2
Two circles of radii 5 cm and 6 cm with common centre are drawn. There is a line AB such that it is chord to both the circles. CD=8 cm. Find the distance of the chord from centre and the length of AC respectively.
3 cm, 1.19 cm
2.55 cm, 2.35 cm
3 cm, 2 cm
2.16 cm, 2.35 cm
Two circles whose centres are O and O′ intersect at P. Through P, a line parallel to OO′, intersecting the circle at C and D is drawn as shown. Then CD=2OO′.
The figure given below shows a circle with centre O in which diameter AB bisects the chord CD at point E . If CD =16 cm and EB = 4 cm, then find the radius of the circle.
Four points A, B, C, D are given on circle. Line segment AB and CD are parallel. Find the distance between AB and CD.
Two circles of radii 4 cm and 3 cm intersect at two points and the distance between their centres is 5 cm. Find the length of the common chord.
In the given figure, lengths of the chords AB and CD are 12 cm and 18 cm respectively and distance between them is 15 cm. Find the radius of the circle.
In the figure, O is the circumcentre of the triangle ABC, AB = AC and the line OD is perpendicular to the side BC. If BC = 24 cm and OD = 5 cm, then find the circumradius.
The length of the common chord of two intersecting circles is 30 cm. If the diameters of these two circles are 50 cm & 34 cm, the distance between their centers is ____ cm.
