The diameter of a circle is twice the radius. When the diameter is 7 metres, the radius is 3.5 metres.
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= 7
Impossible because the diameter of any circle is always twice its radius.
