Diameter = 2 x radius = 18 mm .

A circle with a radius of 50 mm has an area of 7853.98 square mm
Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
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.
13 mm. The radius of a circle is 1/2 of the diameter.
d = 2r = 12 mm
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
12mm - half the diameter.
Diameter = 2 x radius = 18 mm .
