the center point and radius of the smallest circle that contains a geometry. The diameter is a special type of chord that goes through the center point of the circle. (geometry, double precision) STMinimumBoundingRadius( geometry geom ). Sort of like a piece of pizza or pie.Ĭhord - A chord is a line segment that joins two points on the circle. Other Circle Geometry terms Sector - A sector is a section of the circle made by two different radii. Where c = circumference, d = diameter, and r = radius. It's close enough.īack to circumference There are a few handy formulas we will use: The decimals actually go on for a long time (forever), but we will round it off to 3.14. The center of a circle is the center point in a circle from which all the distances to the points on the circle are equal. We won't go into the details right now, but let's just agree to use it and that it works for now. It stands for a number that we use with circles. We use the following formula to figure the circumference: /rebates/2fbasicgeometry-help2fcircles2fplane-geometry2fradius&. So the diameter is two times the radius and the radius is one half of the diameter.Ĭircumference - The circumference is the distance around the circle. This gives you our first math equation for the circle: For the circle below, AD, DB, and DC are radii of. This is the same distance R we used to make the circle in our definition.ĭiameter - The diameter is a straight line that goes across the circle and through the center. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. Terms used in circle geometry Radius- The radius is the distance from the center point to the edge of the circle. Watch as we add in equal distanced points in the movie below: Now pick all the other points on the screen that are the exact same distance R away from point P. Let's pick a point on a flat surface, like this screen, for instance. Okay, so let's start out with the "given point". We can learn a lot about the real world and how it works by understanding circles.įirst, what is the official definition of a circle?Ī circle is a shape that is made up of all the points on a plane (a flat surface) that are the same distance from a given point. There are circles all around us in the real world.
