Arc length = 136*2*pi*r/360
So r = 360*arc length/(136*2*pi) = 425.5 cm
Arc length = 136*2*pi*r/360
So r = 360*arc length/(136*2*pi) = 425.5 cm
Arc length = 136*2*pi*r/360
So r = 360*arc length/(136*2*pi) = 425.5 cm
Arc length = 136*2*pi*r/360
So r = 360*arc length/(136*2*pi) = 425.5 cm

The radial length equals the chord length at a central angle of 60 degrees.
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) .
The measure of the central angle divided by 360 degrees equals the arc length divided by the circumference. So 18 degrees/360 degrees=arc length/(9 feet*2pi). 1/20=arc length/18pi feet; arc length=9pi/10 feet. It's refreshing to answer a question that is written with grammatical accuracy!
If this is a central angle, the 72/360 x (2xpix4) = 5.024

2pi/9 radians or 40 degrees
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
It is certainly possible. All you need is a the second circle to have a radius which is less than 20% of the radius of the first.
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.
The radial length equals the chord length at a central angle of 60 degrees.
The length of an arc of a circle refers to the product of the central angle and the radius of the circle.
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.
360 degrees
The length of an arc on a circle of radius 16, with an arc angle of 60 degrees is about 16.8.The circumference of the circle is 2 pi r, or about 100.5. 60 degrees of a circle is one sixth of the circle, so the arc is one sixth of 100.5, or 16.8.
Well, in degrees, the arc is congruent to its central angle. If the radius is given, however, just find the circumference of the circle (C=πd). Then, take the measure of the central angle, and divide that by 360 degrees. Multiply the circumference by the dividend, and you will get the arc length. This works because it is a proportion. Circumference:Arc length::Total degrees in triangle:Arc's central angle. Hope that helped. :D
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
