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
The diameter is twice the radius.
Radius is from the centre to edge so is 5cm.
5cm since radius is one half the diameters.
The circumference of a circle, if its diameter is 5cm, is about 15.71cm
The circumference of a circle with a radius 5cm is: 31.4 cm
The circumference of a circle with a radius of 5cm is: 31.42 cm
if a radius is 5cm the diameter is 10cm rule- you double the radius
