NO!!! Diameter refer to circles. A rectamgle has a DIAGONAL.
Only circles (or spheres) have a diameter
yes
diameter = 12.56/pi
The diameter of a circle is twice the radius.
Every diameter of the same circle is the same length, and unless someone comes alongand stretches the circle when you're not looking, the diameter doesn't change.So...YES-----------I disagree...No they are not... all circles would be the same size if that were the case.What remains a constant is that all circles are 360 degrees.==================================The question doesn't ask about " ... the diameter of circles ... ".It asks about " ... the diameter of a circle ... ".The diameter of circles is not always the same, butthe diameter of any one circle is always the same.P.S.: This is not the place to debate the answer.The "discussion area" is.
It is: diameter = 31.4/pi which is about 10 units
Circles have a diameter, not length. The diameter of a US cent is 19 mm.
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Since with circles the radius is half the diameter, the diameter would be 6 cm.
A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
