It is not possible to find the exact length since the answer involves pi, which is an irrational number whose exact value cannot be represented in our counting systems. So that the product of any one or more numbers with an irrational number is also an irrational number.

The length is 2*pi*12/6 = 4*pi = 12.56637 meters APPROXIMATELY.

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 radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.

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

89.52 degrees.

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

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

(arc length / (radius * 2 * pi)) * 360 = angle
