diameter
A circle graph shows the different parts of a whole quantity.-Akira
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
it is a circle graph
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
Quarter circle
A chord is a straight line within a circle that divides the circle into two parts - these parts are called arcs.The diameter is a chord that runs through the centre of the circle and divides the circle into two equal parts.
Make a horizontal line and vertical line through the circle. You now have 4 parts. Make a line from the center to the edge of the circle in 3 of these parts and you now have 7 parts.
There are five parts of a circle. They are-1.Radius: It is the parts of the circle that be defined as the distance between the center of the cirlce and a point on the circle.2.Diameter: It is the parts of the circle that be defined as the distance between the two point on the circle which cross through the center of the circle. Note: Every diameter of a circle is a chord; however, not every chord is a diameter. Whether a chord passes through the center determines if it is or is not the diameter.3.Chord: It is the parts of the circle that be defined as the line whose end points are on the circle.4.Secant Line: This line intersects the circle exactly at two points.5.Tangent Line: This line intersects the circle on the point.Thus we can define parts of a circle.
A circle divides a plane into three parts.
Only the diameter can divide the circle in to two equal parts.
Each circle with a different radius (or diameter or circumference) is a different size circle.
