What is the relationship between the chord and the radius of circle?
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
What is a straight line through a circle not going through the middle?
a chord. i took geometry this year. here are some other things that way help. Circle- a set of points that are equidistant from the center of the circle Diameter- a line segment that passes through the center point and has its endpoints on the circle. Radius- a line segment that connects from the center point to the circle Chord- a line segment that has its endpoints on the circle. Arc- a section of the circle's outer points. Semicircle- half of a circle. Central Angle- an angle that has its' vertex as the center point of the circle. Inscribed Polygon- a polygon that has all its' vertexes on the circles outer points. kk :-)
A wire of length 20cm is bent so as form arc of circle of radius 12cm what is the angle subtended at the center in radians is?
When the angle is measured in radians arc_length = angle x radius. So, 20cm = angle x 12cm => angle = 20cm / 12cm ~= 1.67 radians
What is the relation between radius and chord length of circle?
This requires trigonometry If theta is the angle from the center of the circle to the edges of the chord, then chord length = 2Rsin (theta/2)
A circle with radius 2 is placed against a right angle another smaller circle is placed in the gap between the circle and the right angle what is the radius of the smaller circle?
6-(4*(2^1/2))
What is an arc central angle and radius of the circle?
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
What is the relationship between the chord and the radius of circle?
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
How do you draw an arc with a given length and known radius?
The length of an arc equals he angle (in radians) times the radius. Divide the length by the radius, and that gives you the ange. Measure out the angle on a protractor and draw the length of the radius at the begining and end of the angle. Then draw theportion of the circle with its center at the location ofthe angle and extending out to the radius.
How to find length of arc if radius and angle subtended at the center are given?
Full circumference of the circle = (2 pi) times (radius)Arc is a fraction of the full circumference.The fraction is (angle subtended at the center) divided by (360 degrees).If you have the radius 'R' and the angle 'A', the length of the arc is(pi) (R) (A) / 180

What is a central angle of a circle?
the radius
What does perpendicular mean mathematicalywhat is radius?
Perpindicular lines are like the lines in the letter "T". The intersect each other at a 90 degree angle. A radius is the distance from the center of the circle to the circle itself. It is half the circle's diameter.
What angle formed by two radius of a circle?
An angle formed by two radius of a circle? I presume that depends on the inclination of one of the two radius related to the other one.

When the angle is measured in radians arc_length = angle x radius. So, 20cm = angle x 12cm => angle = 20cm / 12cm ~= 1.67 radians
What is a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
What happens between a radius and a tangent in a circle?
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
What is the relation between radius and chord length of circle?
This requires trigonometry If theta is the angle from the center of the circle to the edges of the chord, then chord length = 2Rsin (theta/2)
