By seeing which line goes through the circle all the way.
apparent diameter
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
The diameter by definition because a diameter of a given object is twice its radius.
The diameter of an object is the distance across it, passing through the center. If an object has a diameter of 9.8 cm, it means that the straight line measurement from one side of the object to the other, through the center, is 9.8 cm. This measurement is already provided as the diameter itself.
To find the linear feet in a given diameter, you need to know the circumference (or perimeter) of the object. The formula to calculate the circumference is circumference = π × diameter. Without the circumference, it is not possible to determine the linear feet.
apparent diameter
because the chord can be determine by the diameter and the diameter can be determine by the chord.
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
to cheak the diameter of something
nominal diameter is the original diameter of an object
The formula to determine speed is speed = distance / time. To determine the diameter of a circle, the formula is diameter = 2 x radius.
The diameter is the height: the tip to the toe of an object.
To determine the angular diameter of an object in the sky, you can use trigonometry. Measure the actual size of the object and its distance from you, then use the formula: Angular diameter = 2 * arctan (object size / (2 * distance)). This will give you the angle in degrees that the object subtends in the sky.
The diameter by definition because a diameter of a given object is twice its radius.
The diameter of an object is the distance across it, passing through the center. If an object has a diameter of 9.8 cm, it means that the straight line measurement from one side of the object to the other, through the center, is 9.8 cm. This measurement is already provided as the diameter itself.
You can use a ruler to determine how long a object is
You can determine if an object is magnetic by using a magnet to see if the object is attracted to it. If the object is attracted to the magnet, it is magnetic.
