The diameter is double the radius.
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.
The radius is half of the diameter. If the diameter is 16 mm, then the radius is 16 mm ÷ 2, which equals 8 mm.
24 mm. The diameter is twice the radius.
The radius of a circle is half of its diameter. Therefore, if the diameter is 50 mm, the radius would be 50 mm ÷ 2 = 25 mm.
The radius of a U.S. dime is approximately 10.5 mm. This makes the diameter of the dime about 21 mm, as 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
To calculate the radius of a quarter in millimeters, you first need to know the diameter of the quarter. A U.S. quarter has a diameter of 24.26 mm. The radius is half of the diameter, so you divide 24.26 mm by 2, resulting in a radius of approximately 12.13 mm.
9 mm
3.5 mm
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!
Diameter = 2 x radius = 18 mm .
