Radius = 1/2 of diameter = 19 centimeters.
Diameter of circle = 2 * Radius of the circle.
The radius of a circle is always 1/2 its diameter.
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
Radius = 1/2 of diameter = 19 centimeters.

1 centimeter
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
The diameter is double the radius, and the radius is 1/2 of the diameter.If the radius is 8 cm, then the diameter is 16 cm.
The radius is 8 cm (r = d/2).
diameter = double the radius = 48 cm
just in case 1/2 of the diameter
It is: 2*4 = 8 cm
Diameter of circle = 2 * Radius of the circle.
