radius is half the length of diameter. So the radius will be 3cm.
Thank you.

The circumference of a circle = 2*pi*radius or diameter*pi
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
The circumference of a circle with a diameter of 6cm is about 18.85cm
The answer depends on what the "6cm" refers to.
