From the figure above, find the length of Chord PQ

From the figure above, find the length of Chord PQ

Answer Details

Length of a chord = 2rSinθ2 $\frac{\theta }{2}$

θ $\theta$ = 60º not 30º and radius = 9cm

Therefore, Length of the chord = 2 x 9 Sin60º2 $\frac{60º}{2}$ = 2 x 9 x Sin 30º =  2 x 9 x 12 $\frac{1}{2}$ = 9cm.
