the general formula is arc length is equal the radius times the angle.
s=r<
s=arc length
r=radius
<=angle
That is not enough information.
You Look at the angle the problem gives you
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
The total circumference is (arc length) times (360) divided by (the angle degrees)
A central angle can subtend (form) an arc of a circle. That has an area of 2 x pi x r x (angle A) / 360.
That is not enough information.
It depends on what "this measurement" refers to: the radius, circumference, length of arc with a known angle.
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) .
you will need to know the angle subtended by the arc; arc length = radius x angle in radians
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)
(arc length / (radius * 2 * pi)) * 360 = angle

The lengthÊof an inscribed angle placed in a circle based on on the measurement of a intercepted arc is called a Theorem 70. The formula is a m with a less than symbol with a uppercase C.

angle of arc/ angle of circle (360°) = length of the arc/ total circumference (2 pi* radius) so you just have to find r then so: angle of arc/ angle of circle (360°) *2pi = length of the arc/ radius radius= ength of the arc/ angle of arc/ angle of circle (360°) *2pi not that hard ;)
