Solution

  • Draw a circle of radius r=3.5cm
  • Mark an arc of 6cm from any point on circle on the circumference.
  • Let M be the midpoint of chord AB
(Line passing through M and center O is the perpendicular bisector of chord AB)
MB=3cmOB=3.5cm(OM)2+(MB)2=(OB)2OM=(OB)2(MB)2OM=(3.5)232OM=1.8027cm
