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
12mm - half the diameter.
The radius would be 2.5 mm.
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
9 mm
3.5 mm

radius = 1/2 x diameter= 1/2 x 39.5 mm= 19.75 mm
Diameter = 2 x radius = 18 mm .
the radius is half of a diameter
12mm - half the diameter.
The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places
