Circumference equals 9 and arc length is 1 what is the central angle?
arc length/circumference=central angle/360 1/9=central angle/360 central angle=40
What are the central angles of a circle?
The central angle is the angle that has its vertex at the center of the circle.
Application of relation between arc of length and central angle?
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
What is the central angle of a polygon?
Central angle of a regular polygon is 360/n. n is the number of sides.
How do you find the measures of a central angle?
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
What is a central angle and what is the relationship of the central angle and the intercepted arc?
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
What is an angle formed by two radii of a circle called?
central angle central angle
What is an angle in a circle whose vertex is at the center of the circle?
Central Angle
Circumference equals 9 and arc length is 1 what is the central angle?
arc length/circumference=central angle/360 1/9=central angle/360 central angle=40
How do you find the measure of the central angle?
the measure of the inscribed angle is______ its corresponding central angle
What are the central angles of a circle?
The central angle is the angle that has its vertex at the center of the circle.
How does the central angle compare to the inscribed angle if it is on the same side of a common chord?
The central angle is double the measure.
What is the relationship between the measure of a central angle of a polygon and the measures of an interior and an exterior angle of the polygon?
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
The central angle of a semicircle is what kind of angle?
It's a STRAIGHT angle
How do you find the central angle in a circe?
The central angle of the circle is the angle around a point and so, be definition, it must be 360 degrees.
If a central angle measures 87 and deg then its arc will measure .?
The same as the central angle of the circle
An angle with a vertex at the center of a circle is a?
central angle
