What does a central angle look like?
A central angle is formed by two radii in a circle that extend from the center to the circumference, creating an angle at the center. The vertex of the angle is located at the center of the circle, and the two sides of the angle intersect the circle at different points. The measure of the central angle is defined by the arc it subtends on the circle's circumference. Visually, it appears as a wedge shape within the circle.
What is the circumference of a circle with a length of an arc 28.61 with a central of 120 what is the circumference?
A central angle of 120 is one third of the circle, so the arc length of 28.61 is one third of the circumference. 28.61 X 3 = 85.83
What is the measure of the central angle of a circle with the arc length of 29.21 and the circumference of 40.44?
arc length/circumference = central angle/2*pi (radians) So, central angle = 2*pi*arc length/circumference = 4.54 radians. Or, since 2*pi radians = 360 degrees, central angle = 360*arc length/circumference = 260.0 degrees, approx.
What is 130 degree radius?
A 130-degree radius typically refers to a circular arc or sector with a central angle of 130 degrees. In this context, the radius is the distance from the center of the circle to any point on its circumference. This means that if you were to draw a circle with a radius of a specific length, the arc defined by a 130-degree angle would represent a portion of that circle, covering about one-third of its total circumference.
Will an inscribed angle always have its vertex on the circle?
Yes all inscribed angles in a circle have their vertex on the circumference of the circle. Central angles have their vertex at the center of the circle.
What is central angle of a circular arc equal to twofifth the circumference of the circle?
2/5 of 360 = 144 degrees
How do you find the length of the arc of a circle with only the measurement of the central angle and the Circumference?
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .

How do you find the degree measure of a central angle in a circle if both the radius and the length of the intercepted arc are known?
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
What is the measure of the central angle of a circle with the arc length of 29.21 and the circumference of 40.44?
arc length/circumference = central angle/2*pi (radians) So, central angle = 2*pi*arc length/circumference = 4.54 radians. Or, since 2*pi radians = 360 degrees, central angle = 360*arc length/circumference = 260.0 degrees, approx.
What is an angle whose vertex is at the center of a circle?
A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.

What is the central angle of a circle with an arc length of 29.21 and a circumference of 40.44?
260.03 for A+ if you wanna know how this is how I got it Central angle = (29.21)(360) / 40.44 = 260.03
Will an inscribed angle always have its vertex on the circle?
Yes all inscribed angles in a circle have their vertex on the circumference of the circle. Central angles have their vertex at the center of the circle.
What is the name of a central angle?
A central angle is an angle whose vertex is at the center of a circle and whose sides (or rays) extend to the circumference, effectively subtending an arc on the circle. The measure of a central angle is equal to the measure of the arc it subtends. For example, if the central angle measures 60 degrees, the arc it subtends will also measure 60 degrees.
What is a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
