Neeraj Singh's Problem Solving Experience:
if the length of the chord is 10 cm let us call it as = 2a then a=5.
let the perpendicular distance from the center of the chord=b
given b=4.deriving the formula for radius=(a^2 +b^2)/2b=(25+16)/8=5.125cm
if the length of chord of a circle is 10 cm and the distance from the midpoint of the chord to the minor arc is 4cm how would you calculate the radius of the circle
