13 mm. The radius of a circle is 1/2 of the diameter.
3.5 mm
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
15mm
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
24 mm. The diameter is twice the radius.
12mm - half the diameter.
13 mm. The radius of a circle is 1/2 of the diameter.
If the diameter of a circle is 50 mm, what is the radius?
The radius if the circle is half of its diameter and so 30/2 = 15 mm
15mm. diameter is twice the radius
9 mm
3.5 mm
20 mm. The diameter is always twice the radius.
If the radius of a circle is twice the diameter. The outer diameter of a circle the size of a circle. 32.25 mm = 1.27 inches
Diameter = 2 x radius = 18 mm .
9 mm
