The radius is always at a fixed, unchanging distance from the center of a circle to all the surrounding points.
It is called the hub.
It has one edge. The edge that connects the bottom circle to the cone part.
radius
A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.Yes, it does.
The line from the center of a circle to a point on the circle is the radius.
radius
if you mean the point that starts at the edge of the circle and ends in the center then this is the radius (:
The radius is always at a fixed, unchanging distance from the center of a circle to all the surrounding points.
Yes it is. The radius of a circle is the length of the line from the center to any point on its edge.
there is a center point, an arc, a radius, a diameter, a chord.
You would have to know the length of the radius. The center of the circle is at one end of the radius. If you just know where some part of the radius is, and not that the part touches the circle then you cannot know where the center is without at lest a point on the circumference.
The RADIUS. Other nomenclature for a circle are:- Diameter ; Two radii forming a straight line through the circle centre. Chord ; A straight line from one point on the circle to another point on the circle that does NOT pass through the circle centre. Arc ; Part of the circumference. Segment ; An area inside the circle bounded by two radii and an arc. Tangent ' A line just touching the circle's circumference in ONE place. NB The plural of the noun 'Radius' is 'RADII' , not radiuses. 'Radii' is pronounced 'Ray- dee - eye'. NNB 'pi' is the Classical Greek small case letter 'p' , for 'proportion. It is an Irrational number, but for elementary(school) purposes it is given as the approximation '3.14' or '22/7' Being an Irrational number means the decimals are NOT in any regular order and go to infinity. pi ~ 3.141592.....
It is a chord of which the circle's diameter is the largest.
Not including its diameter it is a chord
The word diameter is a noun. It is any straight line between two points on the circumference of a circle ensuring it passes through the center of the circle.
Picture the center of a circle. The distance from it to the edge of the circle is the radius. The fixed distance from the center to the edge of any part of the circle is radial movement. So radial movement is the circular distance an object can move from a fixed point.
