Circumference of a Circle Now, circumference is the distance around the outside edge of this circle. The diameter of a circle is represented by the letter d.
DIAMETER OF CIRCLE FULL
The distance between any point of the circle and the centre is called the radius. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. Diameter of a Circle Diameter is the full length of the circle running from the edge, through the midpoint, all the way to the other side. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The times they are a-changin'.A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Area: Diameter: Circumference: BookMark Us. Most colleges like to see 3-4 years of high school math so most kids have no choice but to find their way through it. Enter the circle area, diameter, or circumference and it will solve for the other two. Diameter can be found by multiplying the. They probably never were going to need that exact math, but the value for most kids is in the exercise it gives their brains. The length of a straight line that intersects the center point of the circle and reaches to each side of the boundary. When two radii (the plural of radius) are put together to form a line segment across the circle, you have a diameter. When my kids would tell me they weren't going to need the math that was being forced upon them, I always told them they were right. The diameter should be measured in feet (ft) for square. Kristin Trapp (author) from Illinois on October 24, 2011: To find out the area of a circle, we need to know its diameter which is the length of its widest part. You havn't really explained what you do in the equations if you could just do that this article would be even more helpful :) Let me know if you have any other questions.

DIAMETER: the width of a circle (through center). Maybe a drawing will help you to remember these. You will usually just plug in a known radius into the equation to figure out the circumference or you may plug in a known circumference to determine the radius. The formula for the area of a circle is better known in terms of the radius: The radius can be found from the diameter. 1 : a straight line that runs from one side of a figure and passes through the center Measure the diameter of the circle. NOTE: CIRCUMFERENCE: the edge of a circle or the distance around a circle. Diameter a line across the widest part of a circle that passes through the centre. Kristin Trapp (author) from Illinois on January 23, 2012:įizzywoz - If you look at examples #1-#4 at the end of the article you can see how numbers are plugged into the equation.
