Diameter: 2 times 19 = 38 mm
It is: 19/2 = 9.5mm
The diameter is twice the radius. Or The Radius is half the diameter. Algebraically, d = 2r or r = d/2
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
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.
Irrespective of the units of length, be they Metric, or Imperial , the diameter is twice the radius. Algebraically written as d = 2r o r ( d = r + r).
The area is (pi) times (the radius)2 , just as it is in any other circle.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The radius is half of the diameter of a circle
The Radius of a circle is half the Diameter of the circle.
The diameter of a circle is twice its radius.
The diameter of a circle is twice its radius.
