  • 9, A radius of 5cm is the same as a diameter of 10cm.
    True
  • 8, A and B are not in the same-sized circle.
    False => A and B are in the same-sized circle
  • 3, Radius = 5mm => Diameter = 25mm
    False => Diameter = 10mm
  • 2, The diameter is made up of two radiuses.
    True
  • 4, Radius = 12mm : 2 = 6mm
    True
  • 6, A and B is in the same size circle.
    True
  • 7, C and D is in the same circle
    True
  • 5, the distance between the centres of the two circles = 5mm + 12mm = 17mm
    False => 5mm + 6mm = 11mm
  • 10, The distance between the centers of two touching circles that touch inside is the same as the difference between the two radiuses.
    True
  • 1, The diameter is shorter than the radius.
    False => The diameter is longer than the radius.
