Technically there are an infinite number of radii in a circle. A radius is a line from the center of the circle to a point on its edge, and since there are an infinite number of points on a circle's edge there are an infinite number of radii.

Two arcs of a circle are congruent if and only if associated chords are perpendicular?
In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.
What is an unbroken portion of a circle that lies between two points on the circle?
An arc (circumference only), or a segment.
If any two chords are perpendicular do they bisect each other?
Only when one of them is the circle's diameter which is the circle's largest chord.
How many radians in a half circle?
there are two Pi in a full circle so there is only one Pi in one radian.
Does a segment joining any two points on the circle?
Only round the perimeter of the circle (not across its interior) because a segment is a part of a line or curve between two points.
What shape has only two sides?
circle
Why circle is not a 3 dimentional figure?
A circle is not a 3D figure because it only has two dimensions. A sphere is a 3D "circle".
Two arcs of a circle are congruent if and only if associated chords are perpendicular?
In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.
What are the two line segments that contains two points of the circle?
Regardless of where you mark two points on a circle, there's only one possible line segment between them. It's called a "chord" of the circle.
What is an unbroken portion of a circle that lies between two points on the circle?
An arc (circumference only), or a segment.
What divides the circle equally into 2 parts?
Only the diameter can divide the circle in to two equal parts.
What are the two Arctic Circles?
There is only one Arctic Circle.
How do you divide a circle into eight parts using only three lines?
Draw two diameter lines, then draw a circle inside the circle.
What planet is circle by only two moons?
Mars has two moons : Phobos and Deimos .
What is the circumference for a 9 ft by 3.14 circle?
A circle is defined by only one measure, ot two, as in this question.
How do you find the circumference of a circle if you know the radiuss?
This is an easy formula to remember!pi times the radius squared. it looks like this πr2π=3.14 (but it goes on) and multiply that by the radius squared! My 7th grade math teacher thought it was funny to say, but pie aren't square, pie are round! (Cheesy, but it stuck!)
What shape only has one line of symmetry?
A triangle with only two of its sides equal. Also a semi-circle or any incomplete circle.
