Diameters and metres are not directly related. A diameter can be 0.01 meters (small coin), a few metres (merry go round or carousel) to nearly 1.4 million metre (the sun). And there are plenty of objects that are larger still.
The question is like asking "how many metres are 5 heights?"
A typical circle has an infinite number of diameters. Each diameter is a line segment that passes through the center of the circle and has endpoints on the circumference.
the crater averages about 875 meters in diameters
radius
Only ONE... IF it's a round pool. But since diameter is a circular measurement, it would have absolutely NO diameters as a square or rectangular swimming pool. But if you mean Decameters instead of diameters, it would contain 10 since there are 10 meters in one decameter and 100 meters divided by 10 = 10. Or, if you meant Decimeters, 1 decimeter is 1/10 of 1 meter, so there would be 1,000 decimeters in 100 meters.
There is no such unit of measurement as a diameter, a diameter is the length across something. Perhaps you are thinking of a decimetre.
i believe 5/16
5% of 5 meters= 5% * 5= 0.05 * 5= 0.25 meters
The difference between 50 meters and 5 meters is 50 meters - 5 meters, which equals 45 meters.
There are 5000 meters in 5 kilometers.
There are infinite amount of diameters.
I suppose you mean how much is Mercury's diameter. According to the Wikipedia, Mercury has a radius of about 2440 km. The diameter is twice that amount, and if you want to convert that to meters, just multiply it by a thousand.
The ratio of the diameters are the cube root of the ratio of the volumes. Therefore the diameter ratio is 3 to 5. 33 = 27 53 = 125
