The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
Radius of a circle is half its diameter, 1/2 of 5cm =2.5cm
diameter=10cm radius=5cm
The diameter is twice the radius.
if a radius is 5cm the diameter is 10cm rule- you double the radius
Radius = 1/2 of the diameter5 cm diameter = (5 / 2) = 2.5 cm radius
10cm
2.5cm !
5cm
Radius is from the centre to edge so is 5cm.
5cm since radius is one half the diameters.
Radius time 2 equals the diameter.
