the diameter would be 9 you would do 4.5+4.5 and that would = 9
The term used is pi
It is the ratio between a circumference of a circle and the diameter (they needed a number to describe this).
The three most common ways to describe the dimension or size of a circle is either the diameter or the radius or the circumference (perimeter).When the circumference is given then dividing that by Pi will give you the diameter (circumference / Pi = diameter).
The diameter of this circle would be about 9.5m

Diameter and height
The Earth is not a perfect sphere. The diameter varies depending on where you measure it.
the diameter would be 7 inches
The diameter would be approximately 7. In exact figures it would be 7
They use it to describe the relation of the circumference to the diameter
A hockey puck is a one inch (1") thick and three inches (3") in diameter, and roughly 6 oz piece of vulcanized rubber
As vessel diameter decreases, blood velocity increases due to the principle of conservation of flow rate. This relationship is described by Poiseuille's law, which states that blood flow is directly proportional to the fourth power of vessel radius. Therefore, smaller vessels result in faster blood flow velocities.
If you describe a table as being 6 foot, that would normally mean that it is 6 feet long, and rectangular in shape rather than round. Only round tables have a diameter. The term doesn't apply to rectuangular tables.
