<PRE><B>Question 754364</B>
length of chord is 60 cm
half of chord will be  30 cm  (perpendicular from center to chord bisect the chord)
radius of circle is 50 cm 
therefor  it will be right triangle 
whose hypotenuse will be 50 cm and other side half of chord 30 cm
distance of chord from center can be calculate by using Pythagoras theorem
H^2 = p^2 +s^2
p^2 =h^2-p^2
p^2 =50^2-30^2
P^2=2500-900
   =1600
p= sqrt 1600
P =40 cm
ANSWER  40 cm </PRE>
