If "one meter" is the diameter, then the answer is one meter.
A circle with a diameter of one meter has an area of 0.785 square meters.
A 7-meter diameter circle has an area of 38.5 square meters.
The circumference of a 9.5-meter diameter circle is: 29.85 meters. (C = d x Pi)
if a circle has an 18 meter diameter, then it has a 9 meter radius the circumference of a circle is 2(pi)r so the c. would be 2(pi)(9) which is 18pi. (another way to think of circumference is the diameter times pi)
Depends on how big the circle is.

Well, honey, a meter is a unit of length, not diameter. If you want to talk diameter, we're looking at circles, not meters. So, technically speaking, a circle with a diameter of 1 meter would have a diameter of 1 meter. But seriously, who measures diameter in meters anyway?
A meter is a unit of measure, and a diameter is the longest linear distance from one point on a circle to another. You cannot convert from one unit to another. If you know other information about a particular circle, however, you can find the diameter's length in meters, but this value can change depending on the circle.
The circumference of a 31.4-meter diameter circle is about: 98.6 meters.
A 0.5 meter-diameter circle has a circumference of about 1.57 meters.
24 meters diameter is simply twice the radius.
The area of a 9-meter diameter circle is 63.617 square meters.
