15mm. diameter is twice the radius
Well, honey, the radius of a circle is always half of the diameter. So if the diameter is 30 mm, the radius would be 15 mm. It's basic math, darling. Hope that clears things up for you!
radius = 1/2 x diameter= 1/2 x 39.5 mm= 19.75 mm
Well, isn't that just a happy little question! To find the diameter of the circle, we simply need to double the radius. Since the radius is 30 mm, the diameter would be 60 mm. To convert that to centimeters, we just need to divide by 10, so the diameter of the circle is 6 cm.

The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
24 mm. The diameter is twice the radius.
13 mm. The radius of a circle is 1/2 of the diameter.
15mm. diameter is twice the radius
Well, honey, the radius of a circle is always half of the diameter. So if the diameter is 30 mm, the radius would be 15 mm. It's basic math, darling. Hope that clears things up for you!

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 .
