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.
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 a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
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 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) .
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
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 a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
If you only have the central angle of a circle can you find the radius?
If "the angle" means the angle between two radii at the centre, the answer is no. You need to know the circumference first. Then use radius = circumference divided by 2 x pi.
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 is an angle in a circle whose vertex is at the center of the circle?
Central Angle
