Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
Radius = 1/2 of diameter = 4 cm
The diameter is double the radius, and the radius is 1/2 of the diameter.If the radius is 8 cm, then the diameter is 16 cm.
16cm
The diameter is the whole width of the circle across the middle. The radius is the distance from the middle to the edge, so is half the diameter. Therefore the radius would be 8 cm
