# How do you find the length of a diameter?

## How do you find the length of a diameter?

Divide the circumference by pi, approximately 3.14, to calculate the diameter of the circle. For example, if the circumference equals 56.52 inches, divide 56.52 by 3.14 to get a diameter of 18 inches. Multiply the radius by 2 to find the diameter.

**How do you find distance with diameter?**

To calculate the circumference, you can just multiply the diameter by π, which is about 3.142. That gives you the distance for each revolution. Then you can multiply by the number of revolutions per minute. That will give you the distance traveled in each minute.

**What is length to diameter ratio?**

L/D is the ratio of the length of magnetization direction of a magnet (L) to the diameter of the magnetization surface (D). (2)For instance, for a square of 15*15*3 with a magnetization direction of 3, its L/D: 3 / (2 * = 3 /16.92=0.17). The L/D is relatively small.

### Does diameter mean length?

Diameter is defined as the length of a straight line through the center of a circle. An example of a diameter is the length of a line sliced down the center of a pie.

**Is height and diameter the same?**

As nouns the difference between diameter and height is that diameter is (geometry) any straight line between two points on the circumference of a circle that passes through the centre/center of the circle while height is the distance from the base of something to the top.

**Is length a diameter?**

Diameter is the length of a line touching two points on a circle that passes through the center. Regardless what information you are given, you can find out the diameter if you have either the radius, circumference or area of the circle. The diameter is the same as the length or width of any circle.

## What is length vs diameter?

As nouns the difference between length and diameter is that length is the distance measured along the longest dimension of an object while diameter is (geometry) any straight line between two points on the circumference of a circle that passes through the centre/center of the circle. is (obsolete) to lengthen.

**Is diameter width or length?**

Diameter is the length of a line touching two points on a circle that passes through the center. Diameter exists only for circular, or for circle-based objects like a sphere or cylinder, thus the width and length should always be the same.

**How do you measure the diameter of a round object?**

Open the calipers to a width slightly greater than the object they are measuring. If they feel loose and do not stay open, tighten the pivot screw until you feel slight resistance when opening and closing them. Close the calipers onto the object at the point you estimate to be the widest part.

### How do you find the radius of a chord?

You can find the radius of a circle if you have the length and height of a chord of that circle. Multiply the height of the chord times four. For instance, if the height is two, multiply two times four to get eight. Square the length of the chord. If the length is four, for example, multiply four times four to get 16.
