The radius of a circle is half of its diameter
1/2 of the diameter
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
7cm; the diameter of a circle is twice its radius.
If the radius of a circle is 18mm, its diameter is: 36mm
The answer is 9
9 mm
Diameter = 2 x radius = 18 mm .
254.47 square mm
18mm or 1.8 cm
The radius of any circle is its diameter divided in half. So: 18mm/2 = a radius of 9mm
The diameter of a circle is twice its radius
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
