It is 0.8 degrees.
Circumference divided by Pi
Angular measurement between two line, when one of them is surface line and another is the line which connect a point on the surface to the peak of the object is known as angular elevation of that object with reference to the the perticular on the surface.
The diameter of any circle or circular object is (circumference)/(pi) .That's pretty nearly the same thing as (0.3183 x circumference) .Now you know how to easily find it on your own.
A caliper.
Ask ur maths teacher
It is approx 0.8 degrees.
It is 0.8 degrees.
To find the angular size, we need to convert the distance to the object into radians. 4 yards is approximately 12 feet or 144 inches. The angular size can be calculated as the diameter of the object (1 inch) divided by the distance to the object (144 inches), which equals approximately 0.0069 radians.
Diameter.
Since it is a small angle, just divide the diameter by the distance. Be sure to convert everything into the same units first. The answer will be in radians.
30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
A diameter is a property of circular objects. "12 inches" is not a circular object and so cannot have a diameter.
apparent diameter
By measuring the change in angular diameter of the object
above the horizon is the answer
Diameter is equivalent to the width of a circular object. Width is the shorter side of a non-circular two-dimensional object. The longer side is considered the length.
The small angle formula is used for measuring the distance to a far away object when the actual size and angular size are known, or for finding out the actual size of a faraway object when the distance to the object and angular size are known. In arc-seconds: a = 206265 x D/d where a = the angular size of the object in arc-seconds D = the actual linear size of an object in km d = the distance to the object in km 206265 = the number of arc-seconds in a complete circle divided by 2pi In Radians: a = D/d where a = angular size of object in radians
