**How Do You Convert Diameter to Square Inches**

If you know the diameter of a circle you simply divide the diameter by 2 to get the radius. This is because the diameter is twice the length of the radius.... The radius is simply half the diameter and can be measured directly, with a ruler. Once you have that figure, you can calculate the circumference. The circumference is equal to pi times the diameter, or two pi times the radius. Pi is equal to approximately 3.1415 which is close enough for all usual purposes.

A town is not likely to be perfectly circular. However, I suppose you could use the radius of the smallest circle that can circumscribe the town to get some measure of its extent.... Recall that the distance, d, between any two points (x 1, y 1) and (x 2, y 2) is given by the following formula: d = √((x 1 - x 2) 2 +(y 1 - y 2) 2) Assuming that the two given endpoints are on the circle, the diameter of the circle is the distance between these two endpoints.

**Radius & diameter from circumference (video) Khan Academy**

The diameter is twice as long as the radius, so if the radius is 2 inches, for example, the diameter would be 4 inches. If the radius is 22.5 centimeters, the diameter would be 45 centimeters. Think of the diameter as if you are cutting a perfectly circular pie right down the center so that you have two equal pie halves. The line where you cut the pie in two would be the diameter. how to get nice traditional art lines Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter i…s 8, the radius is 4

11/05/2011 · If you select the dimension in either mode you can use Edit > Convert to > (Radius, Diameter, Linear) to switch the radial dimension type. This is normally easier and faster than using Edit Replace or Deleting and Recreating the dimension. how to go from grower to shower Radius is half the diameter. The diameter of a circle is a straight line that passes from one side of the circle to the other through the centre of the circle.

## How To Get Radius From Diameter

Circumference = π × diameter = 2 × π × radius. The circumference of a circle is the distance around it, but if, as in many elementary treatments, distance is defined in terms of straight lines, this can not be used as a definition.

- Recall that the distance, d, between any two points (x 1, y 1) and (x 2, y 2) is given by the following formula: d = √((x 1 - x 2) 2 +(y 1 - y 2) 2) Assuming that the two given endpoints are on the circle, the diameter of the circle is the distance between these two endpoints.
