Answer 2

Heya mate,

Here is your answer,. ⬇️ ⬇️

${ANSWER :-}$

__________

$<i>$ Here, OM = 8cm.
And, AB = 12 cm.

Now, OBM is a right angled triangle.

Again, we know that a perpendicular on a chord from the centre divides it into 2 equal parts.

Thus. AM = 6 cm.

Now ,using pythagoreas theorem,

OB^2 = AM^2 + OM^2
=> OB^2 = 6^2 + 8^2 = 36 + 64 = 100.
=> OB = 10.

➡️ Hence, the length of OB is 10 cm.
