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
The total circumference is (arc length) times (360) divided by (the angle degrees)
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.
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
You Look at the angle the problem gives you
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.
The total circumference is (arc length) times (360) divided by (the angle degrees)
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 ;)
