The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.

A 7 mm diameter circle is the equivalent of a circle with a 0.275-inch diameter.

The radius is half of the diameter. So, if the radius is 7 the diameter is 14.

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"
