the length of a chord of circle of radius 10 cm is 12 cm. Determine the distance of the chord from the center.
(a) 8 cm
(b) 7 cm
(c) 6 cm
(d) 5 cm

Answer 1

Answer:

Radius of the circle = 10 cm. Distance of the midpoint of the chord from the centre of the circle = [10^2–6^2]^0.5 = [100–36]^0.5 = 64^0.5 = 8 cm. Answer is 8 cm.
