Question

ab is a chord of a circle with Centre O and diameter 20 CM. if the length of a b is 12 cm find the distance of a b from the centre o.​

Answer 1

Answer:

8 cm

Step-by-step explanation:

let  apo be triangle

p is mid point of ab

angle formed at p is 90

so,apo is right angled triangle

then ,

(ao)²=(op)²+(ap)²

10*10=(op)²+6*6

op²=100-36

op²=64

op=8

distance of ab from centre o is 8 cm
