what is the distance between two parallel chords of length 32 cm and 24 cm in a circle of radius 20 cm ?
since the chord length = 2 sqrrt ( r ^ 2 - d ^ 2 ) chord length = 32 , r = 20 then we get d = 12 chord length = 24 , r = 20 then we get d = 16 then we add / subtract we get option c ) 4 or 28 answer : c
max(add(sqrt(subtract(power(20, const_2), power(divide(32, const_2), const_2))), sqrt(subtract(power(20, const_2), power(divide(24, const_2), const_2)))), subtract(sqrt(subtract(power(20, const_2), power(divide(24, const_2), const_2))), sqrt(subtract(power(20, const_2), power(divide(32, const_2), const_2)))))
