A diameter is a straight line passing through the center of a circle or sphere, connecting two points on the circumference. Therefore, a circle with a diameter of 1 meter would have a circumference of approximately 3.14 meters (π x diameter). The diameter itself remains 1 meter in length, as it is a measurement of the distance across the circle passing through its center.
A circle with a diameter of one meter has an area of 0.785 square meters.
If the diameter is 1 metre then the radius is 0.5 metre.
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.
Diameter is not a unit of measure. It would be like asking how many inches in 1 highway. However, decimeter is a unit of measure. One decimeter is equal to one-tenth of a meter. There are 3.937 inches in a decimeter.

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

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.
Twice as much as the radius
