A circle of radius 14cm has a chord of length 12cm. What is the shortest distance from the chord to the centre of the circle? Geometry of Circles. the...

The chord is
closest to the center at a right angle to the center. Radius = 14. Chord length = 12

So the answer is $\displaystyle\sqrt{{{{14}}^{{2}}-{{6}}^{{2}}}}=\sqrt{{{196}-{36}}}=\sqrt{{{160}}}={4}\sqrt{{{10}}}$
cm
