If the diameter is 6 inches, then the radius is 3 inches.
Radius = 1/2 of the diameter = 6 inches
Diameter: 2*6 = 12 inches
6 inches. always multiply radius by 2 to get diameter
12 inches because the radius is half of the diameter, and 6 x 2 is 12.
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches
diameter = 2 X radius = 12 inches
12 inches. (6 inches x 2)
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
Radius squared is half of the diameter multiplied by itself. Example: diameter is 6 inches, radius is 3 inches (half of diameter), radius squared is 9 inches (radius multiplied by itself 3 x 3 = 9).
6 inches because the diameter is twice the radius 3+3 = 6 circumference = pi*6 = 18.849 inches
