A rectangular shape cannot have a diameter, which is a characteristic of a circle.
The circumference of the wheel is Pi multiplied by the diameter (0.705). Divide 1000 meters (1km) by that answer - and you'll have your solution !
Which angle formed on rectangular field
Field diameter is calculated by measuring the distance across the field of view of a microscope, then dividing that measurement by the magnification of the objective lens being used. This gives you the field diameter in micrometers.
Anthe is probably Saturn's smallest moon, if you discount the moonlets, with a diameter of about 1km.
The field of view would be 80 times the diameter.
Subtract the square of the width from the diameter. The square root of that is the length.
1km = 1000m 1km > 50m 1km is bigger
To calculate the field diameter of a medium power lens, you need to first determine the field number of the lens. The field number is typically provided by the manufacturer and represents the diameter of the field of view in millimeters. To calculate the field diameter, you divide the field number by the magnification of the lens. Field diameter = Field number / Magnification.
1km = 1000m520m/1km:= 520/1000 or 13/25 of 1km
Magnification is inversely proportional to the diameter of the field of view.
Since a field is rectangular, it has 4 right angles, each of them measuring 90°
