A diameter is a description of a line from one side of a circle to the opposite side. Its length depends on the size of the circle.

A 7-meter diameter circle has an area of 38.5 square meters.
Pi times diameter is your answer. In this case, Pi is approximately 3.14 units and your diameter is 1 meter. So, 3.14 times 1 meter = 3.14 meters. What I like about using centimeters is that your answer is approximately 3 meters and 14 centimeters. This is a rounded answer of course since the approximation of Pi is 3.14 and the decimal part goes on forever.

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 circle with a diameter of one meter has an area of 0.785 square meters.

There is no difference.
1 meter. Radius is 1/2 diameter.
If the diameter is 1 metre then the radius is 0.5 metre.
The volume is 0.7854 m3
This sounds like a trick question as it is a play on words. I believe the correct answer is 1 meter in diameter. It may help if I put it another way... the word "meter" is contained within dia-meter. diaMETER may be easier to see.
The volume of a pipe with diameter of 1 meter and a length of 2 meters is 1.57 cubic meters.
A 7-meter diameter circle has an area of 38.5 square meters.
First of all its not diameter .It is decameter .Now, The conversion between m and dam are given .On finding the relation we get as follows . 1 dam=10 m . THus,1 m=0.1 dam.
If "one meter" is the diameter, then the answer is one meter.
