Since the minor arc is 30 degrees, the major arc is 330 degrees (360 - 30).
So we have:
330 degrees : arc length 10
30 degrees : arc length x
330/30 = 10/x
11/1 = 10/x
x = 10/11
x = 0.9 approximately
So the length of the minor arc is approximately 0.9 units.
If the radius of the circle is r units and the angle subtended by the arc at the centre is x radians, then the length of the arc is r*x units. If you are still working with angles measured in degrees, then the answer is r*pi*y/180 where the angle is y degrees. If r and x (or y) are not available, or cannot be deduced, then you cannot find the length of the arc.
"That would be A minor. Go a minor third below the tonic of the major scale to find the relative minor." Technically, there is no relative harmonic major to the key of C Major. The relative minor scale of C Major would the natural minor scale of A. A harmonic minor scale raises the 7th note of the scale a half step, giving us G#, which is not in the key of C Major.
Find the circumference of the whole circle and then multiply that length by 95/360.
Ursa major and USA minor
It is simply greater than 180 degrees but less than 360 degrees

To find the relative major of a minor key, you can go up three half steps from the minor key. For example, the relative major of A minor is C major.
To find the parallel minor of a major key, you simply need to go down three half steps from the major key. For example, the parallel minor of C major is A minor.
find the arc length of minor arc 95 c= 18.84

To find the relative minor of a major key, you can count down three half steps from the major key's root note. This will give you the relative minor key.
I'm assuming that "c" is short for "circumference". The length of an arc is (circumference)*(360/angle). So the length of an arc in a circle with circumference length of 18.84 is 6782.4/angle, where the angle is measured in degrees.
Count up a sixth from the major (C) to find the minor (A).
If the radius of the circle is r units and the angle subtended by the arc at the centre is x radians, then the length of the arc is r*x units. If you are still working with angles measured in degrees, then the answer is r*pi*y/180 where the angle is y degrees. If r and x (or y) are not available, or cannot be deduced, then you cannot find the length of the arc.
A major minor keys chart provides information about the key signatures, scales, and chords associated with major and minor keys in music.
To determine the relative minor of a major key, you can find the sixth note of the major scale. This note is the starting point for the relative minor scale.
An arc length of 120 degrees is 1/3 of the circumference of a circle
