In a circle, the length of a chord AB is 48 cm & radius is 25
In a circle, the length of a chord AB is 48 cm & radius is 25
cm. Find the distance between centre and chord.
Let AB is chord , O is centre of circle, OC is perpendicualr dran on AB So now C will be mid point of Chord. Hence AC =AB/2 = 48/2 = 24 cm& OA = radius = 25 cm So in Right angle triangle OAC , By pythagorus triplet of (7,24 & 25), OC = 7 cm More Circle Questions
