It is 12/360 times 12*pi = 2/5*pi or about 1.257 feet rounded to 3 decimal places
The length of an arc of a circle refers to the product of the central angle and the radius of the circle.
A central angle is measured by its intercepted arc. Let's denote the length of the intercepted arc with s, and the length of the radius r. So, s = 6 cm and r = 30 cm. When a central angle intercepts an arc whose length measure equals the length measure of the radius of the circle, this central angle has a measure 1 radian. To find the angle in our problem we use the following relationship: measure of an angle in radians = (length of the intercepted arc)/(length of the radius) measure of our angle = s/r = 6/30 = 1/5 radians. Now, we need to convert this measure angle in radians to degrees. Since pi radians = 180 degrees, then 1 radians = 180/pi degrees, so: 1/5 radians = (1/5)(180/pi) degrees = 36/pi degrees, or approximate to 11.5 degrees.
It depends on what information you have: the radius and the area of the sector or the length of the arc.
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
Length of arc = angle (in radians)*radius = (pi/4)*14 = 10.996 cm
-- 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 length of an arc of a circle refers to the product of the central angle and the radius of the circle.
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
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.
The radial length equals the chord length at a central angle of 60 degrees.
If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
If this is a central angle, the 72/360 x (2xpix4) = 5.024
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
(arc length / (radius * 2 * pi)) * 360 = angle
