\nSolution:
\nThe distance of the chord from the centre O
\n\"Samacheer
\n\"Samacheer<\/p>\n

Question 2.
\nThe chord of length 30 cm is drawn at the distance of 8cm from the centre of the circle. Find the radius of the circle.
\nSolution:
\n\"Samacheer<\/p>\n

Question 3.
\nFind the length of the chord AC where AB and CD are the two diameters perpendicular to each other of a circle with radius 4 \\(\\sqrt{2}\\) cm and also find \u2220OAC and \u2220OCA.
\nSolution:
\n\u2206OAC is an isoceles triangle with one angle 90\u00b0
\n\u2234 \u2220OAC + \u2220OCA = 180\u00b0 – 90\u00b0
\n\"Samacheer
\n2\u2220OAC = 90\u00b0
\n\u2220OAC = 45\u00b0
\n\u2234 \u2220OCA = 45\u00b0
\n\"Samacheer<\/p>\n

Question 4.
\nA chord is 12cm away from the centre of the circle of radius 15 cm. Find the length of the chord.
\nSolution:
\n\"Samacheer<\/p>\n

Question 5.
\nIn a circle, AB and CD are two parallel chords with centre O and radius 10 cm such that AB = 16 cm and CD = 12 cm determine the distance between the two chords?
\n\"Samacheer
\nSolution:
\nThe distance between the two chord FE = OE + OF
\n\"Samacheer
\n\u2234 Distance between the chords is 14 cm<\/p>\n

Question 6.
\nTwo circles of radii 5 cm and 3 cm intersect at two points and the distance between their centres is 4 cm. Find the length of the common chord.
\nSolution:
\n\"Samacheer
\nThe length of the common chord AB = AD + BD = (3 + 3) cm = 6 cm<\/p>\n

Question 7.
\nFind the value of x\u00b0 in the following
