Given LN is perpendicular to KN, LN=16 feet m

Without seeing the real diagram, there are two interpretation:

KM is a diameter. But that can't be or else m∠L = 90°.KM is a chord. We know m∠L = 100°

Triangle LNM is tight-angled and tan 55° = 16/NM

NM = 16/ tan 55° = 11.20332...

In the same way, find KN

We now have the chord KM,

Let the radius be R

The angle subtended by a chord at the centre is twice the angle at the circle.

So angle KOM = 200°

By the cosine law

R² + R² - 2(R)(R)cos 200° = KM²R = 19.39057726m.
