14 cm. In a circle, diameter is always twice the radius.
It is 14 cm.
The radius of a circle is half the diameter.
A circle with a radius of 14 meters has an area of 615.75 square meters.
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.
Diameter is twice the radius=14"
Radius of circle: 14/2 = 7 meters
The radius is half of the diameter. So, if the radius is 7 the diameter is 14.
