Question 808179
diameter = 136 
r = 68

chord = 64
1/2 the chord = 32

The perpendicular line drawn from the center of the circle to the chord bisects the chord

the radius , half the chord and vertical segment form a right triangle

(Hyp)^2=		(leg1)^2+			Leg2^2	
Hypotenuse =			68	cm		
leg1=			32	cm		
Leg2=			?			
						
leg2^2=hyp^2-leg1^2						
Leg2^2=		68	^2	-	32	^2
Leg2^2= 		4624	-	1024		
Leg2^2= 		3600				
Leg2=		{{{sqrt(	3600	)}}}		
Leg2=		60	cm
