What does the diameter tell us about the circle?
The diameter of a circle is the distance from edge to edge of a circle passing through its origin or center. Conveniently, it is twice as long as the radius of a circle. If you draw two opposing line segments from the circle's origin to the edge, you just drew the diameter. There are three dimensions most often used to describe a circle:
How do you find the area of a circle given the diameter?
Area of circle given diameter is the area enclosed by a circle of diameter d and is represented as A = (pi/4)*d^2 or Area = (pi/4)*Diameter^2. Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. How to calculate Area of Circle given diameter?

360The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°. For the time being, we'll only consider angles between 0° and 360°, but later, in the section on trigonometric functions, we'll consider angles greater than 360° and negative angles.
What does a full circle equal?
360°A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle. Arcs are divided into minor arcs (0° < v < 180°), major arcs (180° < v < 360°) and semicircles (v = 180°).

What is the difference between the diameter and radius?
The radius is a line connecting the edge of a circle to the center . The diameter is the line that starts on one edge of the circle, passes through the center, then ends at the opposite edge of the circle. The circumference is the distance around the edge of the circle.
How to find the circumference of a pizza?
If this chef wanted to determine the circumference of their pizza, they could take some string and lay it carefully along the outermost edge of the crust of their pizza. Eventually, when the ends of the string met, it would form a circular loop tracing around the pizza. To find the circumference, they could straighten out this yarn and measure its length to find the distance around this pizza.
What is the length of a radius?
In this example, each half of a diameter would, by definition, be the radius. Since a radius starts at the center and ends at a point on the circle, and the center is the midpoint of the diameter, the length of the radius must be half of that of the diameter. The formula is {eq}d=2r {/eq}.

The diameter is formed from the center of one side of a circle to the other, meaning that there are no coordinates since the diameter is always located in the center of the circle.
How to find the diameter of a circle if you don't have the radius?
If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius. Then, you can just multiply the radius by 2 to find the circle's diameter.
