A diameter is one end to other end of a circle passing through centre, radius is line drawn from centre to any side, if we join two radius that form a straight line we get a diameter, all radius of a circle are same, so 2 radius= diameter, diameter =42
2 radius =42
Radius=21 cm
2 radius =42
Radius=21 cm
